TA won't fall

[dubele]

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.:study:

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

I am a TFP addict and I proudly admit it...lol

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
