Re: cacium hardness/ metal control new to me, do I need them
My pool store said I needed 6 lbs of calcium hardness today also. I was also wondering if I needed it? I have never put it in before. All other chemicals were fine. It is a little clouldy for some reason.
Above ground vinyl 7500 gallon
80 calcium hardness
FAC 5
PH 7.2
TA 90
CYA 40
