December 15, 2021 14:00 - 38 minutes - 35.2 MB00:00 - Intro 00:36 - 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 instantly 12:10 - Sharing Eric's screen (alkalinity equilibrium), which can be found on the Orenda Blog, search for Alkalinity 14:21 - 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 sod...
What is Scale? | Calcium Issues, pt. 1
December 08, 2021 14:00 - 34 minutes - 31.6 MB00:00 - Intro 01:57 - 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...
Draining and Diluting a Pool
December 01, 2021 14:00 - 16 minutes - 15.5 MB00:00 - 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 do...
Ways to suppress pH from naturally rising
November 17, 2021 14:00 - 27 minutes - 24.9 MB00:00 - 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 calc...
Water Chemistry Testing: 201
November 10, 2021 14:00 - 28 minutes - 26.1 MB00:00 - 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 fro...
Water Chemistry Testing: 101
November 03, 2021 13:00 - 29 minutes - 27.2 MB00:00 - 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 re...
Introducing the Orenda Help Desk in Pool Service Software (PSS)
October 27, 2021 13:00 - 23 minutes - 21.5 MB00:00 - 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 abo...
PPM and PPB
October 20, 2021 13:00 - 14 minutes - 12.9 MB00:00 - 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...
Concrete Pool Shell Problems | Weepers, Efflorescence, and Calcium Nodules
October 13, 2021 13:00 - 30 minutes - 27.8 MB00:00 - 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 o...
