    New pool test results after 4 days...opinions

    Today's results.
    FC 4.5
    CC 0
    TC 4.5
    TA 100
    Ph 7.2

    I added cya on Tuesday. FC has ranged from 0 on day my electric was finished to 4.5 today. I've used roughly two and a half bottles of bleach thus far. TA started at 110 but has been at 100 rest of the week. Ph started at 7.8, then went to 7.5 and has been at 7.2 the last two days.
    Opinions? Suggestions? All I've added is bleach and cya.

    Looks like you have a good handle on things. What was your target CYA? If it was 30ppm and thus 4.25 pounds, using the calculator, that would lower the pH by 0.56 ... basically exactly what you have seen. It will likely start to climb now that the CYA is dissolved.

    Yeah I put 4 lbs of cya in. Haven't tested for it yet. Figured I'll see what it was after a week and go from there.
