Calcium Hardness Increaser for Swimming Pools – Fast-Dissolving Calcium Chloride for Balanced Water and Surface Protection – Boost Hardness Levels in All Pools Types – 45lb Bucket

Maintain balanced pool water and protect your surfaces with PoolFix Calcium Hardness Increaser — a premium calcium chloride solution designed to raise calcium hardness in all types of swimming pools. Whether your system is plaster, vinyl, fiberglass, or salt-based, this fast-acting formula helps ensure proper mineral levels to support effective pool care. Low calcium hardness can lead to visible surface wear like etching and staining, as well as corrosion of internal components including pumps and heaters. PoolFix helps prevent these issues by delivering fast-dissolving calcium chloride granules that disperse evenly in the water without residue or cloudiness. It’s an ideal addition for mid-season balancing or after dilution events like rain or draining. Maintaining correct hardness not only helps protect your pool’s infrastructure, but also supports consistent performance of other balancing agents like pH and alkalinity. When calcium levels are within range, water feels better on skin and helps prevent the soft or foamy effect caused by low mineral content. It's a simple step that reinforces overall water quality. To use, test the calcium hardness level in your pool using a reliable kit. If levels are below the recommended range (usually 200–400 ppm), calculate the required dose and broadcast the granules directly into the water while the pump is running. With Pooluxe, you get an effective, easy-to-apply solution that helps preserve your pool’s surfaces and mechanical systems all season long.
