Not here it hasn't.
Folks in the desert may see 10% to 15% reduction a month, but it's a non issue for upstate NY.
All the reactions occur on the plates and they DO get hot.There is very high concentration of Cl(atomic state,not Cl2) which immediately reacts with water.There is also very high concentration of OH- that leads to formation of Ca(OH)2 than reacting with CO3-- forming calcium carbonate scale and flakes/slush found in the SWG pools.I started my pool with 30ppm of CYA and after 2 months is 0.Is your statement an opinion or is it based on something more solid?
It was:Degradation of Cyanuric Acid (CYA)Not here it hasn't.

You'll see a 3 to 5 ppm breakdown per month, plus whatever dilution you get from rain overflow. It'll be unnoticeable month to month in the season but likey noticable when you close the pool and walk away for up to 8 months.
How are you testing ? 20 and under is sketchy to read at best with Taylor, and the other methods have long proven their terrible reliability.
We have done thousands and thousands, if not hundreds of thousands of SLAMs since that 2008 thread with no noticable effect on CYA.
It's based on math and measurements. Typically a fairly solid foundation to stand on.
So you measured the temperature of the plates and the chlorine levels at the plate?
Taylor test that goes down to 5ppm.My pool temp is 100 degrees.My point is that chlorine concentration at the plates is very high and may far exceed the SLAM levels.
If that was true than plates would not need to have rare earth metal coatings............
I'm sorry, you appear to be confused. You see, you are making the claim that the water temperature and chlorine concentration are incredibly high at the plate level, so it is your job to measure it to share with the class.
Huh? The coatings are to protect the plates from breaking down from electrolysis. That has nothing to do with heat.
What specific test would that be?
That. That's why your CYA level is going down. No need to stab at random baseless theories, your water is hot. Mystery solved.
Theory is great and I love it personally. But we have a ridiculous amount of real world users not seeing any appreciable CYA loss with SWGs. Myself for one in a similar climate to yours. If it's dry for 2 months, the CYA is rock solid.
Wouldn't artifical heat remove most of the equation without the intense UV needed to raise the temps that high ? Otherwise anyone with a heater would be reporting similar losses as many are running in the 80s.
There is a huge difference between double blind controlled study and observation.That is exactly how most idiotic theories were created....
We see 20+ ppm per month CYA loss in hot tubs all the time. Temporarily heating the water won't have much of an effect on the CYA, but leaving it at a high temperature consistently will speed things along.
Plates don't "break down" from electrolysis.The electrolysis products will react with plates material.You are the one stating that "plates don't heat the water and Cl raises by 1-2 ppm".Where exactly did you get that information?SWG manufacturers state that plates do get hot!
