SWIM Cal Increaser is used to raise calcium hardness in swimming pool water. Low calcium hardness levels could cause the pool water to become corrosive which may result in damage to the pool surface or equipment.

How to Use: Apply directly into pool water with the circulation system running.

Pro Tip: Do not pre-dissolve this product as heat is generated when it contacts water.

Size: 3.5 kilograms
