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

Wildfires and Swimming Pools

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

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.

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

Containing pH vs. Controlling pH

Rule Your Pool ·

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). From the ITZs.12:33 - Example using the Orenda

2021/08/18

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

Combined Chlorine 201: How to reduce combined chlorine

Rule Your Pool ·

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

2021/08/04

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

2021/07/28

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

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

How to Fix 3 Types of Green Pools

Rule Your Pool ·

2021/06/09

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

Why is My Pool Green?

Pillar 4: Minimal Cyanuric Acid (CYA) | Orenda's Four...

Rule Your Pool ·

2021/05/26

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
