    switched to swg

    I switched over to a swg about two weeks ago. Aquarite is at 40%. Here are my numbers;
    FC = 5.5
    CC = 0
    TC = 5.5
    TA = 80
    CYA = 90
    Calc = 130
    PH = 7.2
    Pool water looks great. Should I worry about raising my PH and any other numbers that I should be concerned about?
    Thanks for your time!

    Your PH will come up on it's own. There is no point in adjusting it.

    Everything else looks fairly good. If you have a vinyl liner pool your CH is fine. But if you have fiberglass or plaster your CH level is too low. CYA is a little too high. CYA will come down slowly over the course of the season, and you can probably get by with CYA a little high, but you need to be extra careful not to get algae or there will be challenges.

    Thanks for the reply!
    I have a vinyl liner. Should I take the CYA down a notch or two?

    Thanks,

    Replacing a little water to get CYA down to 80 would be good. It shouldn't take very much water replacement to go down that small amount.
