Balance Pak 300 | 52220BIO

BioGuard Balance Pak 300 is a calcium hardness increaser designed to help prevent equipment corrosion, etching of plaster and wrinkling of liners. Featuring a unique palletized formulation for faster dissolution and less cloudiness, this product is key to preserving pool water balance and consequently maximizing the results from chemical treatments. Low calcium hardness can lead to staining, etching, and distorting of pool finishes; resulting in an abrasive, uncomfortable and hard-to-clean pool experience.
