So I put the following numbers in and the pool calc says I am balanced. PH 8.2, FC 6.5, TA 90, CH 200, cya 85, salt 3400 which gives a csi of -0.02. But I am not at the recommended levels that pool school says I need to be at. I don't get it! PH is high and ch is low. Can someone explain to me so that I can understand if my pool is really balanced? Is my pebble sheen going to be ok with the ch at 200?
