00:00 - Intro00:58 - To reduce alkalinity, use acid. But there are a few types of acid. And what, exactly, does acid do? It converts alkalinity into carbonic acid (dissolved CO2).04:17 - The amount of dissolved CO2 in your water determines the pH.04:36 - Clarifying "carbonate alkalinity" vs. "total alkalinity". 07:45 - The Orenda App adjusts alkalinity automatically for you when you update the CYA level.08:45 - How to actually add acid to reduce alkalinity: do not column pour! Dilute dilute dilute.13:55 - How to deal with tap water with high alkalinity (150+ ppm) or very high alkalinity (200+ ppm).17:16 - Reduce alkalinity slowly. Do not remove more than 20 ppm at a time. Aim for 10-15 ppm of alkalinity reduction at a time. The more dilution, the better.18:12 - To reduce risk of 'tanking the pH' while reducing alkalinity, aerate the water. And there are other ways of stirring up the water without circulating it through the system.20:00 - How to raise alkalinty: Sodium bicarbonate (baking soda) and Sodium carbonate (soda ash). Bicarb is more appropriate for raising alkalinity because it barely raises pH, whereas soda ash will raise the pH significantly for the same alkalinity addition.23:49 - Summary.

Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda00:00 - Intro01:23 -  Introducing Rob Butcher, the CEO of Swim Across America02:02 - Who is Swim Across America? 2022 is the 35th anniversary of SAA.05:52 - The boat for the original swim sank, and it's still on the bottom of the Long Island sound.10:06 - Fighting cancer is personal to Rob.12:32 - The first Intermission in RYP Podcast history. We hereby invite you to join our team.16:26 - The energy of a SAA swim is incredible.19:29 - When SAA makes a gift to a cancer institution or hospital, SAA has a scientific and medical board who helps decide where best to allocate those funds. In particular, patient research for experimental, cutting edge treatments.29:39 - Olympic swimmers show up at almost every swim, and they volunteer their time to be there. In fact, they pay to swim and help raise money.31:49 - We lost an employee last week, Kelly. We want to honor her and she is already sorely missed. She kept our business running and made sure we were able to ship on time, even during the supply chain chaos of COVID. By the time she found out she had cancer, it was too late. It had already spread everywhere. 36:10 - SAA is directly in our industry. The pool industry is predicated on the fact that people need to learn how to swim. It's a life skill.37:26 - Not many people in the industry were competitive swimmers. But you don't have to be a swimmer to be a part of this. You can volunteer, donate, and tell others about it. We'll swim on your behalf.Join your own event, or join our team. It's 100% tax deductible.

00:00 - Intro01:07 - Giving credit where credit is due02:25 - Saltwater pools ARE chlorine pools04:13 - Salt (NaCl) dissolves in water and the sodium (Na) separates from chloride (Cl-). That chloride is what the salt system converts into chlorine04:43 - What a salt cell is and how it works08:45 - Electrolysis converts 2Cl into Cl2, and Eric attempts to read through the three chemistry formulas in order...13:51 - Because Hydrogen gas (H2) does not dissolve, it bubbles off and creates aeration, which leads carbon dioxide (CO2) to also leave, which raises the pH17:00 - All of this chemistry depends on having enough conductivity in the water17:49 - Two factors drive conductivity: water temperature and salinity22:45 - Summary of the episode in just 3 breaths.

What can we expect with the supply chain shortages?05:10 - What can you do NOW to make openings smoother in a few weeks? 08:57 - Most pools with mesh covers (or no covers) will have lower calcium and higher pH than they winterized with.12:55 - A hard reset in the spring is a very good practice. What can you decide to remove from your water?16:22 - We can start removing phosphates and non-living organics now. Addressing metals will have to wait until the water is warm enough. 17:50 - A hard reset puts yourself and your customer in the most advantageous position going into the season.18:36 - Summary - Thanks for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro....by Jarred?02:35 - What is a Standard Operating Procedure (SOP)?07:34 - The root of the word "decide".17:18 - When people do their own thing in a service business, they are incentivized to cover up their mistakes.21:07 - Collective intelligence24:00 - Step 1: Gain control of CYA levels.27:20 - Step 2: Create an LSI floor (foundation) with calcium hardness, and a ceiling with total alkalinity.34:23 - Step 3: Write down your clearly-defined SOP for chemistry and behaviors. Written down processes, such as using a measuring cup and diluting acid, using a thermometer when you test water, etc.36:08 - Step 4: Purge and remove contaminants. Decide to remove non-living organics and phosphates from the water.38:54 - Step 5: Track it. Without documentation, it makes it harder to notice deviations from the baseline.41:46 - Benefits of standardization: Brand benefits43:39 - Benefits of standardization: Personnel substitutions are easier45:57 - Benefits of standardization: Problems will stand out sooner47:17 - Benefits of standardization: Collective intelligence47:58 - Benefits of standardization: Reduced employee turnover48:52 - Benefits of standardization: Better forecasting, which in turn allows for bulk purchasing discounts50:11 - Summary - Thank you for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:43 - Swimming is an individual sport AND a team sport. Individual athletes racing the clock are part of a bigger team. This translates to pool companies as well.04:02 - Let's focus on people. Not the job, not the skills, the people. People are always the most important aspect of a business.04:32 - The benefits of a baseline, such as water chemistry minimums. Standards lead to collective intelligence, the team becomes more cohesive.10:09 - Build a family and team atmosphere. Gather input from employees. They know things you do not.10:45 - A reward system within the team, i.e. "Mojo" the monkey.13:41 - Involve the homeowners in appreciation of your employees too. Example: Southwest Airlines 'kick-tails'17:47 - With more profitability comes opportunities to clean up the brand. Better uniforms, cleaning the trucks, etc. Everyone wants to take pride in their work.19:25 - Increasing the margin for error also helps keep employees. Example: customer adopted the Orenda program and noticed their employees were starting with some 'early wins' and getting compliments early on. More room for error means less frustration when learning.23:24 - Training is available all over the place. Orenda has Orenda Academy, this podcast, over 100 blogs, videos and procedures too. But other companies do too. Manufacturers want to train your people.24:15 - Summary: Let your team build a healthy culture, once you have established a baseline and a family/team atmosphere. ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:44 - Drinks made from plants have natural color from Tannins. Wine, coffee, tea, etc.06:10 - Nothing replaces the importance of physically cleaning organics out of the pool. Leaves, acorns and other droppings will overwhelm chlorine if you do not regularly remove them.10:25 - Tannins can be soaked out of decaying organics. They either stain the surface or discolor the water, or both.12:48 - If you don't clean off mesh covers, decaying organics will release tannins into the pool below the cover. It's not pretty.14:20 - Cleaning up tannin stains and discoloration mostly involves chlorination. But is chlorination the most efficient way of handling tannins? Not in our opinion.15:58 - CV-600 and CV-700 enzymes are awesome for handling tannins. Enzymes devour them.19:05 - How can you identify if it's an organic or metal issue?  You can do the white bucket test. Scoop some water into the clean white bucket and add a bit of liquid chlorine.  If it clears up, it was either algae or tannins (organics). If the water gets darker, it's metals.21:03 - Summary.

00:00 - Intro01:49 - Most people mistake this problem for scale. But it's not scale.05:05 - This is a chemistry issue, not specific to brand of finish or pigment. This is not a cement or pigment failure, it's a water chemistry problem that can be prevented.06:01 - How this occurs during plaster application, exposure and startup.15:36 - How this occurs months or years later,  from aggressive water over time.21:04 - When we get calls about these issues, the answer is not always good news. We are not in the business of pointing fingers at who caused what.25:45 - Two causes of etching: not diluting acid, and using trichlor feeders, especially on pools with auto covers.28:35 - Summary.

00:00 - Intro02:00 - Look up "nodule" on blog.orendatech.com, and you will find articles that show photos of calcium nodules. You can also do an online search of nodules and find plenty of information.04:32 - This is the Orenda podcast, and we believe you should hear both opinions on nodules.  First, the NPC's position.08:08 - Now, the onBalance position.12:42 - Both sides acknowledge nodules are not scale. They are minerals from within (or behind) the plaster surface that come to the surface.17:12 - Water chemistry itself cannot stop nodules once they've started. They are not chemistry problems, in our experience. They are a physical problem with structural weaknesses in cement.20:12 - Summary - thanks for listening!

00:00 - Intro00:36 - Welcome to the team, Ryan Rickaby!01:20 - Review of calcium hardness (amount of calcium carbonate) vs. LSI (saturation of calcium carbonate)04:30 - Soda ash clouds the water instantly12:10 - Sharing Eric's screen (alkalinity equilibrium), which can be found on the Orenda Blog, search for Alkalinity14:21 - When the pH is high enough, carbonate ions (CO3- -) perfectly match with calcium ions (Ca++) to form calcium carbonate (CaCO3).19:10 - If you put 11+ pH soda ash into the water, it will convert bicarbonate into carbonate, on top of the sodium carbonate you just added, which forces an LSI violation locally. So adding soda ash should be added slowly, and pre-dissolved.19:56 - The cloud, it either gets filtered out, goes back into solution when the chemistry normalizes, or it precipitates out as dust.20:27 - Plaster dust26:52 - Carbonate clouding30:12 - Winter dust34:52 - Summary - Thanks for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:57 - Definition of scale: Scale is the hardened deposit of a calcium compound that has precipitated out of solution. 02:30 - Analogy of sugar in a drink. This analogy explains the difference between the saturation of calcium carbonate (LSI), and the amount of calcium carbonate (calcium hardness). 06:33 - Calcium carbonate (CaCO3) is the most common form of scale, by far. But there are other forms of scale: calcium silica, calcium sulfate, calcium phosphate, and probably some other obscure ones we have yet to encounter. They are more difficult to deal with.12:35 - The same amount of 'sugar' (calcium carbonate) can be too much, too little, or just right, depending on other factors in the LSI. The key here is that scale falls out of solution when the water is oversaturated. Carbonate scale occurs over +0.30 LSI.16:10 - When you see scale in your pool, it will always be in the hottest places first. In the case of carbonate scale, it will be in the highest-LSI areas first. Primarily a salt cell or heater. Flakes in salt cells occur because of a localized LSI violation in the salt cell.22:08 - If scale is not on plastic fittings, the face of tile, lights, etc., it's not scale. It must have come from the cement, not the water.25:46 - To chelate or sequester, the water needs to be warm enough (~65ºF or warmer), or else the chemicals will not activate. The warmer the water, the faster these chemicals work.29:06 - How to remove scale32:28 - Summary. Thanks for listening!

00:00 - Intro01:42 - Dilution is not always the solution. But it can be the most practical answer to get certain chemistry levels reduced.06:54 - Evaporation will not lead to dilution, because the dissolved solids stayed behind. Things will accumulate because tap water adds more dissolved solids to the water.07:09 - Dilution is not so much about high Total Dissolved Solids (TDS), it's about what's in that TDS.  Specifically high cyanuric acid, and high calcium hardness.09:55 - You don't have to dilute all at once, it can be done over several weeks or more. You can also let nature dilute it for you (rain and snow).12:40 - If your chemistry is preventing you from maintaining LSI balance or having proper sanitation, draining and diluting might help you simplify your chemistry. Draining/diluting is much better than throwing a whole bunch of other chemicals in the water.15:37 - Summary - Dilution is a good thing in many cases, but it's not always necessary.

00:00 - Intro02:01 - Recap of Henry's Law of differential pressures. Any gas dissolved in a liquid will equalize with that same gas above the liquid.04:36 - If you exceed the pH ceiling, the atmosphere will literally push CO2 back into the water.04:57 - Where does CO2 come from when adding acid? It converts bicarbonate into carbonic acid (dissolved CO2).07:50 - We don't want bicarbonate ions to convert into carbonate ions (at 8.3 pH or higher) because carbonates are attracted to calcium ions, creating calcium carbonate.12:12 - How can we stop the rise of pH? How can we suppress pH?12:39 - Analogy of the beer: what can you do to stop the beer from going flat? Think of it that way. How can you stop (or slow) the loss of CO2?16:36 - Three categories of ways to suppress pH: cover the pool, chemically suppress it (acid feeder, CO2 injector, trichlor chlorine), and have very low alkalinity or high CYA to lower the pH ceiling.18:53 - Explanation of sense-and-dispense acid feeders, and the challenges with them (overfeeding acid).23:36 - If you don't have any of those reasons listed, but your pH is still being suppressed, please contact us! Teach us so we can learn more about this topic.26:25 - Conclusion.

00:00 - Intro01:11 - Things can go wrong in water testing, so let's review the common mistakes and interferences.05:07 - Reagent expiration dates mean nothing if the kit is not stored properly. All test kits have a finite shelf life.09:10 - Bleaching reagents (very high chlorine) can distort other tests too.15:08 - Cold water interferes with accuracy too. Warm the sample before testing.18:48 - Mistakes are common when collecting a sample and taking it somewhere. Grab the sample from below the water surface, fill the clean bottle completely without a big pocket of air in it, and then take it directly to the pool store or lab. The longer you wait, the less accurate the test results.23:29 - A few other items: lighting is important for color comparison tests, and if you notice something is way off, test again and examine your test kit for problems. Practice, practice, practice.26:49 - Summary.

00:00 - Intro - Joe's back!01:44 - Water chemistry testing is important because without it, managing swimming pools well becomes impossible.05:55 - Water testing is not difficult, but it takes practice and some effort to get good at it. It helps to keep a log of your test results!06:31 - How often should you test? It depends on the factor(s), but some should be every week, other should be once a month. Free chlorine may be a few times a week in some cases.13:10 - If you track your results, managing your pool becomes easier because you will notice some trends and you can predict where your water will go.15:36 - There's one more factor that isn't measured with a test kit that is very important: water temperature.20:17 - There are many different ways to test the water. What type of kit is right for you?24:00 - Take care of your test kit! Store it right, clean it, follow instructions, calibrate electronics (if applicable), and don't let reagents expire.27:24 - Get good at testing if you're the one testing the water. It takes practice, but make the effort to be proficient in it. It's an important skill to have.28:26 - Thanks for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro00:49 - Today's episode is about addressing problem pools in the most efficient way02:02 - Introducing Gus Velez, founder of Pool Service Software04:36 - PSS users are pool service professionals07:35 - They had a few chemistry support tickets come in, and they are not chemistry experts. So they went out looking for a partner who can help their users with water chemistry. They found Orenda.10:28 - When you call Orenda, it's most helpful if you give us the right info about the pool. Photos, chemistry history, age of the pool, etc.13:47 - Users can just touch a button in PSS and it sends the pool's information–and the user's question–directly to Orenda.16:32 - PSS also has a web-based dashboard, and business owners can also request Orenda support on behalf of their employees.18:54 - This integration makes our job easier at Orenda, because we have the right information to answer questions faster.20:59 - Thanks for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:59 - PPM = parts per million. It's the density of a given substance dissolved in water. It's the ratio of that substance compared to water. 1 PPM means the dissolved substance is one-millionth of the volume of water.03:47 - PPM = mg/L. Converting from the metric system it makes sense.  1 cubic meter of water contains 1000 Liters. Each liter contains 1000 mL. Then we switch to solids, because we're talking about dissolved substances. 1 mL = 1000 mg.07:00 - Brief overview of chemistry targets that use PPM 10:16 - Phosphates are measured in PPB, not PPM. Parts per billion is one-thousandth of a PPM. 1000 ppb = 1 ppm.11:56 - Conclusion.

00:00 - Intro02:54 - Water chemistry did not cause these problems. These are structural issues.03:54 - Three main problems: weepers, efflorescence, and calcium nodules.04:09 - Weepers are active leaks in concrete, where water is flowing through concrete. Usually this is from behind the concrete shell due to groundwater pressure. But it can also be on a raised wall where the pool itself pushes through a weakness in concrete.06:23 - Shotcrete is applied pneumatically, and the density of it is important. Minimum 4000 PSI.08:07 - Concrete is not waterproof, it's porous.10:02 - When water takes minerals with it to the other side, that's called efflorescence. Usually it's calcium, and forms calcium carbonate on the outside. It's often confused with scale.12:57 - Calcium nodules are another form of efflorescence, but through pool plaster. They happen when moisture is trapped in or behind the cement. The disagreement in the industry is about how the moisture got there.17:24 - In Eric's opinion, calcium nodules are either in the weakest places in plaster, or they're everywhere. It's almost always a waterproofing failure. Water pushes from the back side, in our experience.21:03 - You can still have calcium nodules in perfectly LSI-balanced water, because nodules are really a form of efflorescence. 24:16 - How do we prevent these problems? Prevention starts with proper shotcrete installation, and we strongly recommend waterproofing the concrete shell. At a minimum, the raised concrete parts.26:09 - Proper waterproofing is strongly recommended by Orenda. And we know it's not always necessary with good shotcrete application, but why take the risk? Waterproofing is relatively inexpensive.28:11 - If you have nodules from groundwater, but not active weepers, the best fix is still chipping out the plaster surface, waterproofing the pool shell, bond coating it, and re-plastering it.  It's expensive.28:43 - Recap.

00:00 - Intro02:35 - Jarred is wearing a Slytherin shirt. He's more of a Ravenclaw, TBH.04:12 - Type of pool cover impacts your winterization chemistry (dilution, pH rise)06:51 - Other types of pool covers that are not for winterizing: thermal and solar blankets. They are not safety covers and are not appropriate for winterization.08:40 - Safety covers are designed to support a lot of weight to keep animals and people (and cars) out of pools.10:54 - Mesh covers allow transfer of water and gas through it. This means dilution, and pH rise.16:21 - Don't be afraid of high levels of calcium going into the winter (500+ ppm)17:31 - Solid covers don't allow dilution and CO2 off-gassing17:50 - Automatic covers can complicate things if your pool is heated a few times during the winter to swim, because the LSI goes from one extreme to the other. Surfaces can get destroyed because the water cannot correct itself.22:08 - Solid safety covered pools do not need quite as much calcium as a mesh cover (400+ ppm), because it won't get diluted.25:14 - Adjust chemicals at least a day before putting a solid cover on.  Let the pH naturally rise up before covering the pool.  If not, you need more alkalinity.26:19 - Thanks for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro, reconnect with nature04:48 - Water would naturally seek balance if you just shut your pool off. But that is not advised, because water would correct itself at the expense of your pool.08:04 - Err to the high side of calcium hardness going into the winter.  LSI balance at the coldest temperature is the main priority.08:23 - The second priority of winterizing is keeping the water clean. But winterization kits have nothing to do with LSI...they are mainly chlorine, algaecides and a sequestering agent. Do you really need them?10:11 - You don't need to super shock going into the winter.  Just chlorinate a bit more than normal. As temps drop, less chlorine is needed.10:38 - Sequestering agents and chelating agents (like our SC-1000) do not work in cold water. We don't include ours in our winterization protocol. You'd be better off adding it in the spring or during startup.13:42 - The Orenda winterization kit does not exist.  Chlorinate normally, add some enzymes, then remove phosphates with PR-10,000 a few days before you close. You'll need to clean up the dust and clean the filter.16:05 - Get a thermometer if you don't have one.16:30 - Water is an incredibly powerful element in our world, so we should embrace its natural properties. If you don't get water what it needs (especially when cold), it will damage your pool in search of balance.17:33 - Let your pH naturally rise. If you have a solid cover, give it a week for the pH to naturally rise before covering it. Don't close at 7.4-7.6 and immediately cover the pool, because CO2 won't escape.19:27 - Thanks for listening!  ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:10 - Wildfires burn through forests and convert plant life into basic elements...primarily carbon, nitrogen and phosphorus.02:15 - The closer you are to the fire, the more contamination will get in your water. If you can smell smoke, it's getting into your pool too.03:45 - Prepare for the smoke, ash and debris when fires start. Be proactive.03:59 - Rare instances: helicopters borrowing water from your pool, and fire extinguisher chemicals getting into your pool. Most likely this is a drain and refill.05:47 - Nothing replaces physically cleaning out debris and cleaning the filter. Chemicals will not remove physical debris.07:30 - Enzymes break down carbon non-living organics. Perfect for addressing carbon contaminants like smoke and ash.08:51 - Phosphates should be removed too. Consider PR-10,000 or CV-700 enzyme + phosphate remover.10:02 - Thanks for listening!

00:00 - Intro01:44 - Biggest difference between normal pool days and a pool party: bather load.05:28 - Visit our Second Pillar of proactive pool care, about non-living organics.08:21 - Holy trinity of pools: Circulation, Filtration, and Chemistry. All three suffer during a pool party.13:08 - Prepare water and clean it up afterward. Homeowners have an advantage because they know when the party is going to happen, and they can prepare. Service professionals visit once a week, so they do not have that luxury.17:27 - Best practices: handle the oxidant demand, communicate, and increase chlorine (not shocking, just raising it up to about 5 ppm). Also, clean strainer baskets and vacuum debris out of the pool ahead of time.20:48 - Clean up the toys afterward so the pool can be vacuumed and cleaned faster after the party.23:22 - Thanks for listening!   ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro02:21 - Evaporation is the process of liquid water converting into water vapor (gas). And this process takes energy (heat) to occur.03:40 - Humidity in the air and the difference between air and water temperature (delta T) are the two main factors that determine evaporation rate.05:03 - How evaporation affects water chemistry.  An average pool loses roughly its entire volume of pool water in a given year.06:28 - Difference in temperature between water and air matters a lot. Cold air and warm water evaporates more. 08:58 - Anything in tap water tends to accumulate over time (calcium, metals, etc.). Things not in tap water tend to stay consistent (CYA, salinity, etc.)10:34 - https://blog.orendatech.com/evaporation-and-accumulation11:27 - Evaporation scum/scale line on their tile, above the waterline. Not necessarily an LSI violation, because water leaves, so the saturation of CaCO3 goes up.14:21 - Winterization involves draining water down, and the dilution throughout the winter drastically changes water chemistry.16:52 - Analogy: glass of water. CH = 200 ppm.  Drink half, the CH does not change.  Let half evaporate, and the CH doubles.18:19 - Thanks for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:30 - Controlling pH is not possible. pH moves with anything that happens to the water. It's a reactionary chemistry.04:07 - Many ways for you to balance the LSI. Use the Orenda App and find out what works for you. 05:45 - Disclosure for commercial pool operators with pH limit of 7.8, and those with chemical automation/acid feeders.10:26 - White rings around aggregate means the loss of calcium hydroxide (aggressive water stole calcium). From the ITZs.12:33 - Example using the Orenda app. Let's do this together so you can see for yourself.17:31 - What if we leverage Henry's Law, and use it to our advantage?19:21 - Containing pH means never going RED on the LSI calculator, so the pH naturally rises to its ceiling (Henry's Law), and no further.25:00 - Quick recap of why pH has to rise.  CO2 determines pH, and CO2 has to off-gas to equalize with CO2 above the water (Henry's Law). 29:58 - Stop thinking of pH as something you can control. Focus on keeping the LSI balanced by containing pH.31:00 - Recap. Focus on proper sanitization (FC:CYA) and your LSI.

00:00 - Intro03:15 - Calcium flakes and other deposits in salt pools are very common. You're not alone if your pool has them.05:00 - Our first question when someone calls about calcium flakes: "what is your alkalinity?"10:33 - How salt cells work, from the inside out12:16 - What does the salt cell do throughout the day? What to the percentages of output actually mean?14:12 - Reversing polarity (changing direction of electricity) in between on/off cycles of salt cells. This fractures calcium carbonate into flakes, which blow into your pool.14:53 - Most of the time, flakes are in your spa, or near your closest return to the equipment.15:41 - Flakes tumble around in the pool and smooth out and look more like sno-kone ice.21:31 - Solutions to this problem: balance your LSI, use SC-1000, and operate with lower alkalinity.27:37 - Allow more circulation time. Most scale is formed right after circulation stops (warm, stagnant water with high pH).30:08 - Summary.

00:00 - Intro02:15 - How do we get rid of combined chlorine? Do we just let chlorine do its thing?02:49 - Two categories of how to reduce combined chlorine: chemically and physically.03:30 - Two chemical options: breakpoint chlorination and supplementing chlorine with enzyme or a non-chlorine oxidizer shock. But enzymes and non-chlorine oxidizers do not directly reduce combined chlorine...only chlorine can.15:06 - Physically removing combined chlorine is done with secondary systems.  Oxidizers and UV sanitizer.  Ozone and AOP are oxidizers that destroy both nitrogen compounds and formed chloramines. UV can only destroy formed chloramines.23:43 - If you have a heavy bather load, a secondary system makes a lot of sense.24:30 - Being proactive means finding the source of nitrogen and addressing that.  Check deck cleaners, any algaecide or other product containing ammonia (or ammonium) and keep them out of your pool.------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro00:59 - This will be complex chemistry, but very simplified.02:07 - What is combined chlorine? What does chlorine "combine with"?05:32 - Combined chlorine is an indicator of your chlorine falling behind, and the byproducts are the cause of bather discomfort, irritation and sickness.06:00 - The pool industry uses the term "chloramines" generally to describe all of these combined chlorine byproducts.12:06 - Chloramines, far more than pH, are behind bather discomfort, eye and throat irritation, etc.16:12 - Even if you have a bromine pool, similar chemistry occurs (bromamines).21:27 - There is no chemical way to get rid of nitrogen byproducts without chlorine combining there.  There isn't a natural enzyme or other chemical that can break down nitrogen compounds.28:00 - Nitrogen in your water means your chlorine will be tied up dealing with it.28:21 - Thank you for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:33 - We're in an muriatic acid shortage. Thanks, COVID.02:21 - Two specialty acids: modified Muriatic Acids for less fuming: AcidBlue and AcidMagic. 03:06 - Muriatic acid is a diluted form of Hydrochloric acid (HCl). It is 31.45% HCl or less.04:14 - Sulfuric acid (H2SO4) is sold in 38.5% concentration. It is comparable in dosing to standard 31.45% HCl. It takes just 2% more sulfuric acid to equal muriatic by volume.09:36 - Sodium bisulfate (NaHSO4) is sold in 93.2% concentration. It is also known as "dry acid", or in pool retail stores, "pH down" or "alkalinity down". It is safer to handle than liquid acid, but needs to be pre-dissolved before adding to the pool.11:48 - Let's talk about sulfates (SO4--) or (SO3--).12:05 - One gallon of 38.5% sulfuric acid leaves behind 47.1 ppm of sulfates in 10,000 gallons.13:19 - One pound of 93.2% of sodium bisulfate leaves behind 9.6 ppm of sulfates in 10,000 gallons, plus salt.14:58 - even in perfectly LSI-balanced water, if you have high enough sulfates, you can still have etching of cement. The sulfate ion (SO3--) can become the dominant ion and kicks carbonate off of calcium (Ca++) and create calcium sulfate.  Enough calcium sulfate can precipitate a sharp crystalline scale.18:08 - The only way to reduce sulfates is to drain and dilute.  Unless you have Reverse Osmosis (R.O.) available. If you're going to use sulfuric or sodium bisulfate, you must regularly schedule dilutions to avoid sulfate problems.19:53 - Sulfates and metals can combine to create that infamous 'rotten egg' smell. We think of it as sulfur, but it's usually iron sulfate or some variant.21:08 - The third alternative for pH reduction is injecting carbon dioxide (CO2). It reduces pH but does not reduce alkalinity. In fact, alkalinity tends to rise due to excess lye from chlorine.22:18 - Acid only introduces more CO2 (to reduce pH) is to burn through alkalinity and convert it into carbonic acid.  And Joe thought I was asking a trick question. There is no CO2 in acid.24:39 - One pound of CO2 is equivalent to 32.8 fl.oz. of standard Muriatic Acid for pH correction.27:08 - Summary------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro02:57 - How to we make use of the limited chlorine we have?03:33 - The chlorine shortage explained (by Joe, so it's better)06:58 - Chlorinate at a time that direct sunlight does not hit the liquid chlorine. Either in shade or at night.09:06 - Don't hoard liquid chlorine. It degrades over time, and don't be that person. Your peers and neighbors need chlorine too. 10:22 - What else can be done? Secondary oxidation/sanitization can supplement chlorine.12:34 - What about deliberately slowing down chlorine? (Intentionally raising CYA)15:02 - If you raise CYA on purpose, you can do that, but you should remove phosphates and non-living organics to further optimize the slower chlorine that you have.15:55 - Keep nitrogen compounds (like ammonia or urea) out of your pool. 19:28 - If you're using algaecides, be aware of their byproducts. All of them have byproducts that will eventually conflict with chlorine and reduce it.21:14 - Summary------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:31 - Green water from calcium/alkalinity imbalance. Add calcium.03:08 - Copper. Figure out where the copper is coming from (and stop it), then remove copper.04:51 - SC-1000 is not a stain or metal remover. It is a chelating agent that needs to be used in conjunction with a citric/ascorbic acid and a metal filter/remover.07:17 - Algae. Chlorine (HOCl) is the best algaecide. Orenda does NOT make any algaecides.14:20 - Remove debris from a green pool, because piles underwater can protect algae from chlorine.18:45 - Liquid chlorine is the preferred chlorine method for green pool cleanups.19:46 - Reminder: never mix different types of chlorine!23:25 - Green pool cleanup process (in order): remove debris. Netting, brushing, vacuuming. Super-chlorinate, add PR-10,000, then CV-600 or CV-700 enzymes.26:21 - When do we add enzymes? Some add them same day, some add the next day. Both seem to work.31:00 - Recap: first, figure out why your pool is green. It may not be algae.33:23 - Thank you for listening!------------------------------------Connect with Orenda Technologies Website: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:43 - This pool wasn't an opaque green, it was translucent, tinging green.02:09 - We know of at least three reasons pools turn green.03:11 - We could safely rule out copper for this customer.03:43 - Jarred is a popular guy (phone rings).04:50 - The next day, the water was perfectly clear and blue, by increasing calcium relative to alkalinity.05:48 - We don't know why, but if you have too little calcium hardness relative to alkalinity, the water can turn green (but clear).06:18 - Dr. McNamara: Optimal ratio to inject CO2 is 4:1 (calcium to total alkalinity). If you're under 3:1, water can start to tinge green.10:43 - The white bucket test (add chlorine to green water and observe color change)18:08 - If you have algae taking over your pool, your algae is outpacing the killing rate of chlorine.19:12 - Control what you can control. CYA and chlorine, phosphate levels (indirect relationship, but important). What really matters is your free chlorine and CYA.24:00 - Wrapping up with two more topics:  CO2 feeders and Potassium Monopersulfate. Both can fuel algae growth.27:21 - Summary: pool can turn green for three reasons: copper, calcium/alkalinity imbalance, algae.27:55 - Thank you for listening!------------------------------------Connect with Orenda Technologies Website: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

00:00 - Intro01:19 - What is CYA and why do we use it?04:54 - Hot temperatures do NOT mean you need more CYA. Temp has nothing to do with sunlight protection and CYA. But chlorine does get used up faster because it works better.10:52 - You do not need a lower pH to have strong chlorine (%HOCl) when you have CYA in your water.12:00 - Percentages of HOCl without CYA are pH-dependent. With CYA, that no longer applies.15:57 - Overstabilization = too much CYA relative to Chlorine19:39 - Oversabilization is an accumulation problem, usually from stabilized chlorines Trichlor and Dichlor.19:59 - One pound of trichlor in 10,000 gallons of water adds 6-6.5 ppm of CYA. It adds up quickly.23:30 - How often should we be testing for CYA?26:36 - Enroll in Orenda Academy™ for more information------------------------------------Connect with Orenda Technologies Website: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

Or you could just throw a lot more chlorine at the problem if you ignore them.16:18 - Growth/reproduction rate vs. killing rate of sanitizer(s)16:46 - Phosphates will be within algae's cell walls.

00:47 - Where's Jarred? Oh yeah, we lost that recording... oops.01:18 - "Stabilized" refers to two different things: sunlight protection for chlorine, and safer storage and handling.03:10 - What are the dangers of having too much Cyanuric Acid (CYA)?06:15 - Advantages of dichlor over trichlor?07:49 - How much CYA does trichlor put into the water? Answer: 6 to 6.5 ppm per pound, per 10,000 gallons of water. Two 3" tabs = one pound of Trichlor.09:23 - Do you even know how high your CYA is? If you're over 100 ppm, did you take the time to dilute the sample? And even if not, you should dilute your pool and lower your CYA regardless. It's already too high.10:46 - Trichlor lowers (or suppresses) pH, and lowers alkalinity gradually. You need higher alkalinity in your pool to account for this.12:25 - Never put trichlor in the skimmer! Connect with Orenda Technologies Website: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/ ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comHelp Center: https://ask.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

Of all types of chlorine, Calcium Hypochlorite (Cal Hypo) might be the strongest, but it is also the most volatile to handle. Even its fumes can rust just about anything in your garage or storage container. In this episode, Eric and Jarred discuss Cal Hypo and the strategies you may need to adopt to properly manage this powerful chemical. If you are having issues with cal hypo because of calcium drift up, high pH, or otherwise, our boys have your back. BE AWARE: Different types of chlorine are volatile if exposed to each other. They can cause fires and literally explode. Never store two different types of chlorine in the same enclosed area. Always handle with care and caution.------------------------------------ Connect with Orenda Technologies Website: https://www.orendatech.com Help Center: https://ask.orendatech.com Blog: https://blog.orendatech.com YouTube: https://www.youtube.com/user/OrendaTechnologies Facebook: https://www.facebook.com/orendatech/ Instagram: https://www.instagram.com/orendatechnologies/ Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

It's a short episode this week as we dive into a new topic: different kinds of chlorine. The next few episodes will focus on liquid chlorine, calcium hypochlorite, trichlor, and salt generated chlorine in that order. As a point of order, we should also tell you this: NEVER mix or store different kinds of chlorine together. ------------------------------------ Connect with Orenda Technologies Website: https://www.orendatech.com Help Center: https://ask.orendatech.com Blog: https://blog.orendatech.com YouTube: https://www.youtube.com/user/OrendaTechnologies Facebook: https://www.facebook.com/orendatech/ Instagram: https://www.instagram.com/orendatechnologies/ Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda
