I have been trying to lower my TA and have managed to get it from 200+ down to 180 with 1 gal of muriatic acid but it seems i should get it lower. But the calculator doesn't tell me to add anything further. Why?
frustratedpoolmom said:You are using the calculator wrong, and/or don't seem to understand how to lower the TA...
You calculate a dose of muratic acid to lower the PH to 7.2. Then you begin aerating the water. The acid will lower BOTH the Ph and the TA. The aeration will raise the PH back up to 7.6ish. Then you repeat the acid addition and aeration, noting the change in TA with each acid addition. This process can take awhile - depending on your source for aeration it can take several days. Eventually the TA will drop into range, and the aeration gets your PH where it needs to be.
Hope this helps.
Correct.Thinkly said:I think someone answered the question and apparently the answer is that I have to just keep aerating until my pH rises and then I can resume adding acid to reduce TA?
Correct?
