Thank you, I haven't tried to lower the baquacil level, just still trying to lower the ph, using muriatic acid, just wondering if I should start now or wait until levels get lower, my pool is 30 ft round, 21,200 gal, sand filter, and I have a well, but don't want to drain anymore than I have to because of strain on the well, I know I will have to refill as I backwash. Thanks for any and all help!
