    Free Calcium Hardness Tests

    We have an AG vinyl and have found that we really don't use the R-0010, R-0011L and R-0012 chemicals - plus, it appears our CH remains stable anyway. All three bottles are 3/4 full and I just bought them last June. Would anyone like for me to ship them to them?

    I would keep them. Even if everything is good now and appears stable it CAN change. While low calcium is not a problem with liner pools high calcium is! You should still be testing it every month or two.
