Calcium hardness too low

Calcium hardness that is too low in your spa water can lead to aggressive water that damages surfaces, equipment, and internal components. When calcium levels are insufficient, the water tends to become corrosive, which can cause premature wear and tear on the heater, pumps, and spa walls. Products to increase calcium hardness help restore optimal water balance, thereby ensuring better protection of your installation, increased comfort for bathers, and more stable and pleasant water on a daily basis.
