Calcium Balance Guard is a premium calcium hardness increaser formulated to restore and maintain correct calcium levels in swimming pool water. Low calcium hardness can cause pool water to become aggressive, leading to plaster etching, surface deterioration, and corrosion of metal components. This product safely raises calcium hardness to recommended levels, helping to protect pool surfaces, fittings, and equipment from long-term damage.

By improving calcium balance, Calcium Balance Guard stabilizes overall water chemistry and supports a balanced Langelier Saturation Index (LSI). Properly balanced water reduces stress on pool finishes, heaters, pumps, and heat exchangers, extending their lifespan and reducing maintenance and repair costs. Once applied, calcium hardness remains stable for extended periods, requiring minimal re-dosing under normal pool conditions.

Calcium Balance Guard is suitable for all pool types, including plaster, fiberglass, and vinyl-lined pools. It is easy to use when pre-dissolved and added as directed, and works alongside regular sanitizers such as chlorine. This long-lasting formula is ideal for seasonal correction or routine pool care, helping maintain a healthy, well-protected swimming pool year-round.
