    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.

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