    High TA

    I am currently working with pool used by the school during the day and the public in the evening. don't know how to get the TA down to where it ought to be.
    PH- 7.4
    FC- 3.0
    CC- .8
    TA- 325
    CH-375
    CYA- 0
    Use a BECSys5 chemical controller
    Test Kits- Taylor K-1518 for chlorine, Taylor K-2005 for PH, TA, and CH
    need some sound advice.
    Thanks

    Welcome to TFP!

    Assuming you have a regular water replacement schedule, normal for a public pool, and naturally high TA fill water, then there is nothing you can do about the TA level. It is going to be high no matter what you do. All you can do is maintain the PH somewhere in the 7.3-7.4 range with frequent acid additions. Acid feed automation is likely your best choice.

    Measuring your fill water TA, if you haven't already, is a good step.
