Draining and Diluting a Pool Dec 01, 2021

Show notes

00:00 - Intro

01:42 - 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. Thanks for listening!

Ways to suppress pH from naturally rising Nov 17, 2021

Show notes

00:00 - Intro

02:01 - 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. Thanks for listening!

Water Chemistry Testing: 201 Nov 10, 2021

Show notes

00:00 - Intro

01:11 - 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. Thanks for listening!

Water Chemistry Testing: 101 Nov 03, 2021

Show notes

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!

Introducing the Orenda Help Desk in Pool Service Software (PSS) Oct 27, 2021

Show notes

00:00 - Intro

00:49 - Today's episode is about addressing problem pools in the most efficient way

02:02 - Introducing Gus Velez, founder of Pool Service Software

04:36 - PSS users are pool service professionals

07:35 - 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!

PPM and PPB Oct 20, 2021

Show notes

00:00 - Intro

01:59 - 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. Thanks for listening!

Concrete Pool Shell Problems | Weepers, Efflorescence, and Calcium Nodules Oct 13, 2021

Show notes

00:00 - Intro

02:54 - 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. Thanks for listening!

Pool Covers and Winterization Oct 06, 2021

Show notes

00:00 - Intro

02:35 - 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-gassing

17:50 - 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!

Closing your pool the Orenda way Sep 29, 2021

Show notes

00:00 - Intro, reconnect with nature

04:48 - 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!
