    Pool numbers after a week

    O.K. pool has been open a week and here are the numbers.

    FC-8
    CC-0
    PH-7.4
    TA-60
    CYA-50
    Borates-30

    Should I be raising the TA some? Will adding more Borax do this?

    Before you decide to raise the TA, watch your pH every day for about a week. If it doesn't drift up or down I wouldn't do anything to the TA. If it drifts down then raise the TA just a bit.

    If you raise TA, raise it with baking soda. Borax will raise PH a lot and have only a small effect on TA.
