HTH Calcium Plus gives pool owners an easy and effective way to boost their calcium hardness into the 200 -500 ppm range, preventing corrosion damage to pool plumbing, surfaces and equipment. Its granular formula dissolves quickly when added directly to pool water, avoiding time-consuming pre-dissolving beforehand. Plaster pools are especially vulnerable to etching and staining from low calcium hardness, and Calcium Plus is the perfect way to protect them. After use, your pool water will be much safer for your physical pool as well as swimmers, who will no longer experience eye and skin irritation from low calcium hardness levels. This product, like all HTH products, is made in the USA to ensure quality, allowing you to buy with confidence.

Ingredients

HTH Calcium Plus contains a blend a calcium chloride and other chemicals that effectively boost your calcium hardness level into the the safe 200-500 ppm range, protecting your pool and swimmers from its corrosive effects.



Product Use

Use this product to boost your pools low calcium hardness level into the optimal range, protecting your pool plumbing, equipment, and surfaces from corrosion damage and giving swimmers much more comfortable water quality.




Directions

Have your pool water analyzed to determine how much Calcium Plus will be required for your pool.  Generally, 1 pound of Calcium Plus per 10,000 gallons of pool water will raise hardness by 10 ppm. 


1.  Add Calcium Plus directly to the pool by broadcasting over the surface of the pool with the pump running.


2.  If a large amount of HTH Calcium Plus is required (more than a 50 ppm addition) add in 1/3 increments, allowing 4-6 hours between additions.
