    Where should TA level be?

    I have a newly replastered pool about 6 weeks old (dark grey colorscapes).
    These are my current readings. (20,000 gal pool)
    FC =3
    PH = 7.8
    TA = 80
    CYA = 60
    CH = 360
    I am using the BBB method after startup pool guy completed his 1 month service (required from plaster co. for warranty).
    I am constantly having to add muriatic acid on a daily basis to lower PH within range but TA tends to drop to 70.

    Should i be more concern with TA being it stays on the lower end of acceptable range?

    Should i add baking soda to bring TA to middle of acceptable range (100)?

    What is best way to add baking soda to pool?

    I'm not overly familiar with plaster myself but reading through this Start Up New Pool Plaster may have the answers you seek.

    You are just fine where you are. We recommend TA be between 70 and 90 for a plaster pool with no SWG.
