Poolife Calcium Plus is used to increase the calcium hardness of swimming pool water. Low calcium hardness may cause the pool water to be corrosive, resulting in corrosion of pool surfaces and equipment. 

Directions

1 lb per 10,000 gallons of water will raise calcium 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 Poolife Calcium plus is required (more than 50 ppm addition), add in 1/3 increments, allowing 4-6 hours between additions.
