    Question Pool Time Calcium Hardness Increaser

    Can anyone tell me if this product (sold by Home Depot) is calcium chloride or calcium chloride dihydrate? Unfortunately there is no indication on the label.

    Thank you.

    I googled the product name and MSDS and found the following list of ingredients:

    Component CAS-No. Weight percent
    calcium chloride 10043-52-4 75 - 97 %
    sodium chloride 7647-14-5 1 - 2 %
    potassium chloride 7447-40-7 2 - 3 %
