To achieve maximum balance of pool water and to avoid erosion of surfaces, your pool water’s total calcium hardness should be between 200 and 300 ppm. Maintaining balanced calcium hardness will ensure better bather’s comfort and protect your pool equipment.

Directions for use:

1. Check total calcium hardness using a testing kit. The ideal recommended level is 200 to 300 ppm.
2. To increase total calcium hardness by 10 ppm, dissolve in a bucket of water 130g of Calcium Plus per 10,000L of pool water. Add to the pool.
3. Check calcium hardness levels regularly to make necessary adjustments.
