    I have a new AutoPilot and my CYA is 120. The pool store says this is fine, especially in the Arizona sun. What do the experts on this site think?

    IF you don't have any problems with CC, I would say, DO NOT let it get any higher. I would recommend to let it come down to under 100 ppm on it's own. 80 ppm is good.

    Hi,

    I think that whoever told you
    that is an Idiot

    We get pretty hot here in
    Australia and we never run
    our CYA that high with a SWG.

    That's double what we run. I'd
    take it down. You can never have
    your pool water too perfect

    Regards,

    Michael Silvester

    CYA from 60 to 90 is often recommended for a SWG. With CYA at 120 you will need to keep your FC level higher, maybe 5 or 6, it is workable but not ideal. I would plan on lowering your CYA towards 80 or 90, but you don't need to be in a rush to do it right away if you haven't been having any problems. The crucial thing is that you don't do things which will continue to raise your CYA level, like using dichlor or trichlor.

    I agree that you should get it below 100 ppm. 60-80 is ideal but even 90 is livable.
