    TA won't fall

    My TA was 110 and I wanted to get it down. I have put in a total of 16 cups of baking soda....two doses at 8 cups each over two days. Yet, my alkalinity seems to be the same. Here are my readings:

    FC 1
    CC .25
    CH 320
    PH 7.8
    CYA 55

    Pool just opened and first time this year lowering TA. Last year, I lowered it many times with these dosages. So, I don't get why it won't budge.

    You need to lower PH to 7-7.2 with MA which also lowers TA. Then let PH aerate back up. When PH is up to 7.8-8.2 then repeat until you have tour TA where you want it.

    Baking Soda is used to RAISE TA.

    Very good. I was going to come back and post that, but I got busy doing stuff.

    In addition to stopping the baking soda that raises the TA and using MA to lower instead. You need to get some chlorine in there.

    I had a little trouble keeping everything straight in my mind when I first started the bbb method. Had to keep reading pool school over and overt till it stuck.

    My pool is my baby. I love learning everything I can to make her sparkle. TFP has educated me well in the last 2 years. I don't post very often but I try to read everything I can to learn more!

    I may be addicted to TFP

    there are a lot of moving parts. Just take it slow and if you have to re-read before you add something there is no harm.

    Take a look AT&T eh article pooldv posted about lowering TA
