Morning, I am new to the forum I have some questions about water balance with Salt water pools.
I have been playing with the Pool Math Guide and have been reading all the pool guide info supplied by the forum and I am kind of confused about a few things.
Why is it recommended to keep a high CYA level on salt pools? (70-80) In the summers here in Phoenix the pool water will be 90 degrees on average and based on the Pool Math my CSI reading will become corrosive with a TA of 60 and a PH of 7.5 if the CYA level is at 70, in the winter no problem. It seems like with higher CYA levels I have a very small window to adjust PH. If I kept the CYA at 50 year round keeping my pool balanced seems to be a little simpler. I try my best to keep my PH at 7.8 and as low as 7.3 in the summer because the heat just eats through everything here plus, as you will see in my readings below calcium can become an issue very quickly if I don't stay on top of the PH and TA. How do you keep the CYA levels in check if they creep over the 80 mark? Im pretty sure all chlorines have some CYA in them.

PHOS 1000 - - - I know its stupid high, and I am trying to get it down. I have no idea how it got so high, water is a month old.
CH 390 - - - - PHX water is high in calcium. Nothing I can really do about it. Other than keep an eye on TA and PH weekly

PH 7.5 - rises to 8.0 by end of week. I am adding a half gallon of acid weekly to maintain
