Increases calcium hardness levels in pool water. Proper calcium levels protects pool surfaces and equipment.
- Raises calcium hardness
- Pure flakes minimize clouding in pool water
- Prevents long term damage to vital pool components
- Easy to use application
- In vinyl and fiberglass pools, calcium hardness levels should be between 150 - 250 ppm
- In pools with plaster or similar surfaces, calcium hardness levels should be between 250 - 350 ppm
