- Maintain a range of 225-300 ppm for plaster pools (175-225 for vinyl, fiberglass & non-masonry pools.)
- As a general rule, use 6 lbs. of Calcium Plus per 10,000 gallons of pool water. This will boost calcium hardness levels by approximately 50 ppm.
- Add Calcium Plus directly to the pool by scattering it over a large area, allowing the filtration system to spread it throughout the pool.
