Protect your hot tub and maintain balanced water with Leisure Time Calcium Booster. This fast-dissolving granular treatment raises calcium hardness to the recommended level, helping prevent corrosive water that can damage spa equipment, plumbing, heaters, and acrylic surfaces. Maintaining the proper calcium hardness is an essential part of balanced water chemistry and helps extend the life of your hot tub.
Water with low calcium hardness can become aggressive, causing it to seek minerals from metal components, grout, and other spa materials. Leisure Time Calcium Booster restores the proper calcium level, reducing the risk of corrosion while creating more stable water conditions. When used as part of a complete water care program, it helps protect your investment and supports consistent water balance.
Ideal for use after filling your spa with fresh water or whenever testing indicates low calcium hardness, Leisure Time Calcium Booster is compatible with chlorine, bromine, ozone, saltwater, mineral, and biguanide sanitizer systems. Regular testing and proper calcium levels help ensure cleaner water, longer-lasting equipment, and a more enjoyable soaking experience.
