Increases water hardness to prevent foaming, equipment corrosion and scaling.

Features:

• Helps maintain proper calcium hardness level of 150-250 ppm
• One pound of GLB Calcium Hardness Increaser will increase the calcium hardness 10 ppm in 10,000 gallons of water

Compatible With:

• Chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.

Applications:
Normal:

1. Determine calcium hardness level. It should be between 150-250 ppm.
2. If the level is below 150 ppm, add CALCIUM HARDNESS UP by distributing the product over the water surface. 1 lb. of CALCIUM HARDNESS UP will increase the calcium hardness 10 ppm in 10,000 gallons of water.

Tips:

• Properly balanced water will prevent the formation of scale deposits and eliminate the corrosion of metal pipes and fixtures.

In general, the calcium hardness level should be 150 ppm to 250 ppm.

If the level is below 150 ppm, add GLB Calcium Hardness Up by distributing the product over the water surface.

One pound of GLB Calcium Hardness Up will increase the calcium hardness 10 ppm per 10,000 gallons of water.
