Posted some info other places but I really need to know before this gets to causing damage - how much Borax to raise PH? Do not need ALK raised so not using soda ash - the bleach calc program only gives borax info for algaecide purposes and does not address just the ph. Mine is falling fast, alk is always too high 160 now, so don't want to go there wish soda ash. Yes, I can put a fountain in there to lower alk and PH will go up too, but that is a time consuming thing and the alk does not bother me as much as the huge ph drop. I am worried about damage to the liner, etc. Help help!
