    Default 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
