Hi, I've been a BBB customer for a couple of years now and it is going great but I'm battling a rising PH level I can add acid to get it down to 7.6 and it gets it in check, but after 10 days or so I go back to 8.0 plus. I add acid and repeat the process. My TA levels stay pretty constant at 70 and Chlorine levels are easily maintained. My current readings are FC = 4.0, CC = 0, PH = 8.0, TA = 70, CYA = 50. I keep my circulating jets just barely making a wave to force trash over to the skimmer baskets so I don't aeration is a cause??? Do I need to lower TA or lower PH down to 7.2 or so? Any advice would be greatly appreciated.
