CarlD said that borax WILL raise TA. Is it just a little? I'm battling high alkalinity in my fill water all the time (300++) so I'm paranoid about adding anything that will increase TA once I get it into range. But PH of 7.2 seems a little low. But if aeration stops increasing Ph at 7.2, then I have to use something else, right?
