    Calcium Hardness

    Do I have to go to a pool store and buy there products to control calcium hardness or can I buy what I need at a hardware store?

    Re: Calcium Hardness

    Are you trying to increase or decrease your calcium hardness? As mentioned, above, pool details and fill water details are helpful.

    Re: Calcium Hardness

    In some areas calcium chloride is sold as an ice melter, but in many areas you need to go to the pool store.
