Calcium Hardness Increaser - 8lbs

(Calcium) Hardness Increaser is a product used to raise the hardness level of your water. When water has a low hardness level, the water becomes very corrosive and can cause your pool's plumbing and/or equipment to corrode. In addition, a low hardness level can cause staining in your pool. To safe-guard your pool, be sure to add calcium hardness increaser when the hardness of your pool water drops below 150 ppm.
