    TA and CH adjustments - my final numbers

    After five weeks of work to move my TA down and add borates, I believe I've settled into my groove:

    FC 2.5
    CC 0
    PH 7.8
    TA 70
    CH 360
    BOR 50 (using strips, color a little less than 50)
    Salt 4300
    Temp 83F
    CYA 30

    I made the last adjustment yesterday, 25# of Borax, 1.5 gall acid, and 45# CaCl to hit these numbers.

    I believe I'm done - and will now enter maintenance mode, keeping the pH between 7.6 and 7.8.

    Am I missing anything? Other suggestions?

    The stickies and forum feedback is great. Thanks for all the tips on TFP!

    That looks excellent.

    I have two little double checks you can do are to make sure that everything is perfect. First, FC should always be at least 2, particularly in the early evening (which is when FC tends to be lowest). Second, PH should rise from 7.6 to 7.8 only very slowly, once a week or less often.
