    Ph keeps raising

    So per testing done this evening using Taylor kit, FC =7.5 (10 ml sample test) CC= 0, TA = 110 CYA =80 but pH is back up to 8.0. I have added a total of 5 gallons of 14.5% muriatic acid over the last three weeks. this has helped reduce my TA from over 200 but the pH was also down to 7.6. Any thoughts?

    Seems fine other than needing to lower the pH again.

    As you use MA to lower your pH it also helps bring your TA down some. That will also help your pH drift. When you want to raise the pH you can use aeration, it won't raise the TA again.
