Filtrite Hardness Increaser – Protect Your Pool with Balanced Calcium Levels
Maintain optimal water balance and safeguard your pool surfaces and equipment with Filtrite Hardness Increaser—a fast-acting calcium booster designed to correct low hardness levels in your swimming pool.
This powerful formulation contains high-purity calcium chloride, which effectively increases calcium hardness in your pool water to prevent corrosive conditions that can cause long-term damage to pool linings, fixtures, heating systems and filtration components.
Low calcium levels can lead to water becoming aggressive, drawing minerals from surfaces and resulting in etching, pitting, and costly repairs. By maintaining the recommended calcium hardness range of 200–500 ppm, Filtrite Hardness Increaser helps to extend the life of your pool while promoting safe, comfortable, and crystal-clear water conditions.
Whether you use town water, rainwater, or bore water, this hardness increaser is a must-have for protecting your investment—especially in concrete or tiled pools.
