Calcium Plus Calcium Plus raises the calcium hardness of swimming pool water. The ideal calcium hardness range is 200-500 ppm. Maintaining calcium hardness below 200 ppm may cause corrosion of metal and plaster surfaces. Useful Tips: Test calcium hardness monthly and add this product if calcium hardness is below 200 ppm. Use convenient dosage chart on product label. If a large amount of Calcium Plus is required (more than a 50 ppm addition), add in 1/3 increments, allowing 4-6 hours between additions.
