Thanks for the fast reply. I was going to lower it only since I need to bring the PH up a little but do not want my ALK to go up with it. I figured if I lowered it to 100 or 110, then when I add the borax the ALK won't go up past 120. My PH right now is about 7.2 and I'd like to get it up to 7.4 and keep it there.
