Customer Reviews
Bare Ground CalPlus is a calcium increaser for swimming pools that brings soft pool water to a normal calcium hardness level. CalPlus helps prevent corrosion, etching and pitting of concrete surfaces. It also prevents damage to the pool equipment. Scattering about 1.25 lbs. per 10,000 Gal. of pool water will raise the hardness of water about 10 PPM. Measuring pool water regularly and treating as needed will keep the pool water well balanced at 200-400 PPM.
