From doing a search I think I know the answer to this but I want to be sure. My TA is low at 70, but my PH holds steady right at 7.8. It has been this way for months. Should I just leave it and not worry about it?
I used to add acid to lower PH to 7.5 but then I felt I was getting obsessed by it. So I let it creep back up to 7.8 and it has been there ever since.
