I have a in ground 13471 gallon plaster salt water pool. My last readings today using TF 100 are:
FC - 0
CC - 0
PH - 7.5
TA - 120
CH - 325
CYA - 60
Salt - 3400
I have been fighting to get CYA up to 75, this month I put in total of 4 lbs of dry using sock and 3 quarts of liquid and still has not improved. I also can't keep my FC up either. I have to add chlorine to the pool manually to keep it at the recommended levels. I did the overnight test where I check the chlorine level at night, then check again in the morning but only lost 0.5. Any ideas? Thanks.
