Draining and Diluting a Pool

Rule Your Pool ·

2021/12/01

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

Ways to suppress pH from naturally rising

Rule Your Pool ·

2021/11/17

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,

PPM and PPB

Rule Your Pool ·

2021/10/20

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

Concrete Pool Shell Problems | Weepers,...

Rule Your Pool ·

2021/10/13

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

Closing your pool the Orenda way

Rule Your Pool ·

2021/09/29

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

2021/09/08

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

Evaporation and Accumulation

Rule Your Pool ·

2021/09/01

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

2021/08/25

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).

2021/08/11

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
