I just recently did a complete drain and have been working to get my PH inline. It seems to keep going up after I work it down with MA. I've been adding acid for a few weeks, as my PH would come down to 7.6 the work its way back to 8 a few days later. Just wondering if this takes some time to level out or am I missing something? I've only about 2/3 of a gallon of acid in a three week period.
FC - 3
PH - 7.8 ( it was 7.6 the other day)
TA - 100
CYA - 30
