    PH Keeps Increasing

    Split from ph-keeps-increasing-t66544.html Please start your own thread when asking a question, rather than hijacking Thanks, Butterfly

    i am having the same issue. same test kit. new pool (water added july 2013). started on trichlor, switched to bleach when i found this site, CYA was 80 now it's 45.

    here are all the numbers from tonights test:
    FC 7.0
    CC 0.0
    pH 8.0
    TA 100
    CH 110
    CYA 45


    is it normal to have to add acid once a week even when the TA comes down? is this where borax might help?

    thanks admitted pool novice here.

    Lower your PH with acid and your TA should come down a little also. If PH drifts up to the high end again repeat. Your PH might like a little lower TA.

    You just made a switch to bleach. It may take sometime for everything to settle in.

    The borax won't help you, it raises PH.

    Only once a week? You're lucky!

    Every pool has its own personality, and yours just isn't one of those set-it-and-forget-it ones. As you keep adding acid to control pH, the TA will slowly drop and the time interval between acid additions should increase.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    +1 what Richard320 said.

    Forget borax for now....not applicable until your pool "settles in"....maybe in a couple of weeks.
