latest testing shows that my pH is a bit on the low side. so, after reading all around here I *know that I should add some borax...except when I put my info into the bleachcalc to see how much it tells me to "add 13.6oz of sodium carbonate (soda ash NOT borax)" ?!?! I thought you added borax to raise pH if your alk was in range? am I missing something or just having a blond moment?
