Protect your pool’s infrastructure and extend the life of your equipment with E-Z Clor Calcium Hardness Increaser (4 lbs). Low calcium levels can lead to "soft water," which becomes aggressive—leaching minerals directly from your pool’s plaster, grout, and stone surfaces, while also corroding metal heat exchangers and fixtures. This concentrated granular formula effectively raises the calcium hardness of your water, creating a balanced environment that prevents costly etching and pitting. Simple to apply and fast-dissolving, E-Z Clor provides the essential mineral foundation needed to maintain crystal-clear water and a pristine pool finish. 

Key Features

• Surface Protection: Specifically formulated to stop the erosion of plaster, tile grout, and pebble finishes caused by low calcium levels.
• Equipment Longevity: Helps prevent the corrosion of metal components, including heaters, ladders, and pump seals, by balancing water chemistry.
• Concentrated Formula: High-purity granular flakes allow for precise dosing and rapid integration into the pool water.
• Reduces Staining & Scaling: By maintaining an ideal calcium range (typically 200–400 ppm), it helps prevent water from becoming corrosive or forming unsightly scale.
• Essential for All Pool Types: Crucial for plaster, gunite, and concrete pools, and highly recommended for vinyl and fiberglass to protect metal hardware.
• Easy Application: Dissolves quickly when added directly to the water or pre-dissolved in a bucket, ensuring no cloudy residue is left behind.
