I'm going insane here. I've followed directions to lower the TA of the pool. The PH has gone down, and my TA went from 110 to 90 the first round. Now I'm waiting for the PH to go back up to 7.6 and its taking forever. Is this normal ? Did I do something wrong. I went to get rid of using the pucks or any powder for my pool because I had a huge CYA and CH problem. I want to use bleach only. With that in mind, I want to get the TA around 70-80 ppm. Does it usually take hours to get the PH back up. I have my Waterfall and aerator on.
