    Would someone run numbers for me please? Lowering TA

    Does anyone have ten minutes to use their Pool Calculator for me today? My laptop is being weird, and I cannot get the Pool Calculator to work for me. DH is unreachable, and if I go clearing caches and fiddling with my computer, he will be upset with me.

    I wish to lower my TA. Here are my numbers. How much MA 31.45% do I need to add that will lower my TA, but not send my pH lower than 7.2 in the first dosing?

    23,600 gallon pool
    FC is 5.4
    CC < .2
    pH is 7.6
    TA is 120
    CH is 320
    CYA is 20 (intentionally this low, for the Chemtrol)
    Borates at 50
    Salt is 3330
    Pool temperature is 84 degrees

    Thank you very much for your help. I want to get going on this somewhat lengthy process.

    (If I enter my figures into Pool Calculator on this machine, the laptop/calculator tells me I have only 23 gallons in my pool and that I'm going to raise the TA by thousands! Yikes! )

    I get 55 ozs, about 7 cups 31.45% MA to lower pH from 7.6 to 7.2.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    I get 81 oz. Since you have 50 ppm borates it takes more than normal.
