I had to turn up my SCG all the way up, and should not have to.
My TFP SWG pool was at 70 CYA last year, and has, in fact, been 100% trouble free and crystal clear.
So I checked my CYA level for giggles, but I was under the assumption you can’t lose CYA unless you lose water, which I have not.
CYA showed as below 30! It was stable all last year at 70. Can CYA Just disappear?
I bought brand new reagents and the test still show d belo 30.
Is there any chemical reaction that is somehow normal that eats CYA?
