In The Swim Calcium Hardness Increaser is designed to maintain the proper calcium hardness levels in your pool water, essential for preventing surface corrosion and scale buildup. When calcium levels drop below 150 ppm, pool surfaces can become damaged and water clarity diminishes. This product raises calcium hardness efficiently by approximately 50 ppm for every 6 pounds added per 10,000 gallons of water. Containing an average of 94% calcium chloride, it helps prevent aggressive or corrosive water conditions that can harm pool surfaces, lights, and ladders. The fast-dissolving granules are easy to apply—simply measure, pour, and circulate the water. It is important to keep calcium hardness below 400 ppm to avoid scaling issues. This increaser also supports maintaining balanced water chemistry alongside pH and alkalinity adjustments. Ideal for swimming pools, it ensures your water remains clear, balanced, and safe for swimmers while protecting your investment in pool equipment and surfaces.
