    Drats, TA is too high

    My pool is requiring a little more acid than I wish, which happened to me before, the solution then was to lower the TA to 50 and things behaved much better all summer long, but that time I just let the TA fall by itself and this year that's not really happening as quick as I would like & I don't want to keep adding acid every 3-4 days
    I want to lower the TA to 50 and just thought I'd run things by you guys to be sure I'm not missing something & that you don't have your usual excellent advice

    pH 7.6
    FC 7
    CC 0
    TA 60-65 (TA was 70 on 6/2/2014 = 18 days ago)
    Target TA 50: To lower TA you reduce pH to 7.0-7.2 with acid and then aerate to increase pH

    Lowering TA involves aeration/acid method found in Pool School. Simply follow that article.
