    question on TA level

    For the last 3 years since getting my first pool, I have to add acid to get the TA level down a bit due to partial spring refill.
    Our city water has a TA of 375 or so.
    Last week I added 48 oz. of acid and lowered the TA from 130 to 110 with some aeration for a couple days using a fountain pump.
    My reading yesterday
    PH 7.4
    TA 110 or 120, seems to fluctuate
    CYA 40
    FC 3.6--before adding 12% chlorine to get to 5PPM
    borate 30
    Comb. chlorine 0
    PH usually drifts back and forth from 7.2 to 7.8 throughout the summer
    Should I not worry about 90 being a magic number to attain at pool opening.Pool never had algae and I run pump 8 hr. daily.
    Thanks.

    As long as your pH remains fairly constant with only minimal rise, you can leave the TA alone. No need to get too worked-up about it unless your pH is rising like crazy every few days. Have a nice weekend.
