After the initial testing and fixing, here is test result. I am planning to bring the TA and CYA up. Also adding salt to bring it up to 3400. Do I need to add calcium as well? Accordingly to Pool Math Calculator, I need to add some calcium chloride. Wondering if my current level is OK.
pH = 7.5
Free Cl = 3.5
Combined Cl =.5
Calcium H = 325
TA = 50
CYA = 40
Salt =3000
Temp = 74
