Mineraluxe Calcium hardness Plus
- Mineraluxe Calcium hardness Plus
- Calcium Plus is a highly refined, calcium-rich mineral designed to increase the hardness level of spa water. This product, which comes in the form of a clean white prill, is used when calcium levels are low to bring them back up. This helps prevent premature deterioration of spa surfaces, including synthetics and vinyl, and unnecessary corrosion of equipment and metal surfaces. Calcium hardness also plays an important role in ensuring that the overall mineral balance is correct, which improves comfort, chemical efficiency and the cost of maintenance.
