Ben, thanks for your help I do have a couple of questions though.....1)the pool store is trying to sell me chemicals to lower phosphates,,,, unless i misunderstood what i've read hear I thought those were a gimmick.
2) I do not understand borates ,,,,I thought that was just another term for alkalinity. 3) per the best guess chlorine chart should I go to 25 PPM?


Thanks Papa
