TREATMENT TO INCREASE WATER HARDNESS for Swimming Pool Water.
Prevents corrosion of metal surfaces and erosion of pool surfaces
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 a balanced calcium hardness will insure better bather’s comfort and protect pool equipment.
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 130 g of CALCIUM PLUS per 10,000 L of pool water. Add to the pool.
3. Check calcium hardness levels regularly and make necessary adjustments.
