Poolife Calcium Plus (20 lb)
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.
1 lb per 10,000 gallons of swimming pool water will raise calcium hardness by 10 ppm.
- Add Calcium Plus directly to the swimming 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.
