My husband is trying to raise the PH so we can add Yellow Out to get rid of the algae in our pool. The chlorine is very high, but he can't get the PH over 7.2. Added lots of Borax, but numbers won't budge. We have had ongoing algae problems except for 3 years we had SWG, but the cell needs to be replaced (we can't afford the $500 right now) so we are back to old style chemical management. Recently found this site. I am reading everything and realize we need to adjust our pool chemical management. Thanks for all the info!!!
