    Question about pH test results-

    On 5/25 I tested and these where my results

    CL 2
    pH 7.2
    TA 90

    So I added 174 oz bleach and 54 oz borax (per pool calc) at bring pH up to 7.5- where I would like to keep it at

    Tested the next morning 5/26

    CL 5
    pH 8.2 IT WAS DRK PINK!


    Tested this morning 5/28

    CL 4
    pH 7.8 (is definately not as dark as it was!)
    TA 100

    My question is should I add m/a to try to bring the pH down to 7.5 or should I just leave it since it seems it's coming down gradually on it's own? I don't want to mess with TA- not so worried about it being 100, just don't want it to go up.

    If it's coming down on it's own, I'd let it keep drifting down until it holds steady again. Just test once daily and see where it lands.

    I agree with MikeInTN. As long as PH is between 7.2 and 7.8 and not headed rapidly towards leaving that range, then just leave it alone.

    Let the pH drop on its own. Each pool is an individual system and seems to find an equilibrium at which it wants to run. My pool wants to be at pH = 7.5 and so, when it gets there after startup, I leave it be.

    I agree, as long as it stays within 7.2 - 7.8 . I've found with mine that if it's a tad low, I raise the TA by 10 until the pH stabilizes around 7.4 - 7.6 . Usually with TA = 110, my pH stays right at 7.4 .
