Thread: Calcium hypochlorite?

    Calcium hypochlorite?

    I was planning on shocking my pool to raise chlorine level to proper range of 8 ppm. My question is if I use hypochlorite shock will that raise my CYA or just my calcium hardness? How much will a bag raise my CH?
    My chemistry is

    FC = 2.8
    PH = 7.6
    TA = 80
    CH = 210
    CYA = 120

    20,0000 gallon plaster pool
