Pool is 6 months old and I have fought high pH and high TA from the beginning. My numbers as of yesterday are:
FC 5
pH 7.8
TA 150
CH 290
CYA 35
Salt 3100
There is some scaling on the water line tile just above the water line. I believe that's due to the pH and TA being too high for too long. I am in the process of lowering pH and aerating to get the TA down and I have added CYA granules to raise that number. Is there anything else I should be doing?
