Description

Natural Chemistry Spa Calcium Increaser is designed to increase calcium hardness levels in spa and hot tub water. Maintaining proper calcium hardness helps protect equipment, plumbing, heaters, and interior surfaces from damage caused by low-calcium water conditions.

Low calcium hardness can result in corrosive water that may contribute to equipment wear and surface deterioration over time. Spa Calcium Increaser helps restore balanced water chemistry while supporting long-term spa protection and performance.

The fast-dissolving formula is easy to apply and works well for new spa startups, water changes, and routine water balancing. Regular testing and adjustment of calcium hardness levels help maintain optimal water quality and equipment longevity.

Pro Tip

Always test calcium hardness before treatment. Maintaining recommended hardness levels helps prevent both corrosion from low calcium and scale buildup from excessive calcium.

Installation Tips

With the circulation system operating, add the recommended dosage according to water test results. Allow the product to dissolve completely and retest calcium hardness before making additional adjustments.
