I don't want all of you to think I am doubting your advice, I am just trying to learn the reasons why I am doing something. We plan to have a pool for many years and I hope to be able to manage it on my own. That was my biggest problem with the pool stores. They would just hand me a print out and a handful of chemicals and tell me to add all of them. But, they never could really explain why and sometimes they would ignore certain things I would bring up like CYA, but then other times it was important.

What all does the CYA do? My pool seems to be holding chlorine at the 3-5 range consistently without dissipating. I was under the impression that the only purpose for CYA was to help you maintain chlorine, which I am doing. Is that right?

Also, I agree Intex is probably not the experts on pool care. I only posted what the manual said because people said I should consult that. According to them, my chlorine is too high already. The manual says I should have a max of 3 ppm. I typically have closer to 5.

I appreciate all of the help!!
