    Pool out of whack

    OK, update on the war.....I can see a dime in the deep end (very clear)
    Latest numbers
    FC 7
    CC 1 (I have never had CC's before------although I saw one at the pool store The new VW CC
    Ph 8
    TA 120
    CYA 0 tested it last night 2X and once this morning

    I originally had a CYA of appx 90, turned over about 6700 gl for an estimated drop of 20 to 70. Pool store tested the cya and came back with 30. We have had a boatload of rain and I backwashed to waste enough to get the skimmers skimming again.
    What do I adjust first?

    Thanks in advance
    1) The size of your pool in gallons = 33,500 16x32x40 L
    2) The type filter you have = 300lb Sand
    3) IG
    4) If it's IG, vinyl liner
    5) pump is 1.5hp

    Use some muriatic acid to drop the ph to 7.5 first, then add enough CYA to bring it to 40.
