Okay, this is probably a simple question, but I haven't been able to find the answer in a search (admittedly a cursory one...).
How, exactly, does TA affect pH?
I'm keeping my TA right around 100 ppm, and am seeing my pH creep up from 7.5 to 7.8+ within 2-3 days.
I understand TA has a buffering effect on pH, i.e., keeping pH from changing drastically and quickly, but will decreasing my TA keep my pH from rising so quickly? Or is that not the way it works?
