Poolife Calcium Plus raises the calcium hardness level of your swimming pool. Prevent corrosion of your metal and plaster surfaces by maintaining a calcium level in the range of 200-500ppm.
Dosage
1 lb per 10,000 gallons of water will raise calcium hardness by 10 ppm.
Directions for Use
Add Calcium Plus directly to the pool by broadcasting over the surface of the pool with the pump running.
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.
