    three weeks post plastering my TA is dropping

    Hi, I am feeling great because this site has already helped me solve one problem in no time time flat and I am am finally feeling good about my pool!

    Here are my current numbers.

    ph 7.8
    TA 60
    FC 4
    TC 4-5 (I guess I need a better kit)
    CYA 30
    CH 260

    I plastered my pool 3 weeks ago. I read in several places to keep my ph 7.2-7.4 for a month. I have been adding muriatic acid twice a day and have kept my ph right at those values. Yesterday my TA was 50 with a 7.2 ph putting my CSI right at the bottom level of acceptableness.

    So I let the ph ride up to where it is today.

    My questions are now that it has been 3 weeks since re plastering should I just let the ph ride up closer to 8? I will still need to add acid clearly, Will my TA continue to drop putting me close to my CSI lower limits?

    I suggest you let your pH rise to about 7.8 (not 8!) and then drop it back down to 7.2 - 7.4 range.

    You can add baking soda to increase your TA to about 80. Things should start to level out soon.

    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.
