Description
BioGuard Balance Pak 300 is a calcium hardness increaser for pools. When calcium is too low, it can become corrosive to equipment, often causing O-rings to become brittle and crack. Low calcium hardness can also cause staining or distorting in the pool's finish. Calcium levels typically stay stagnant in pool water once set, but it is imperative to the longevity of your pool and equipment to properly balance its calcium level.
