Your Spa water might look sparkling clear, but your water may also contain a hidden danger to your equipment and surfaces: low calcium hardness. Maintaining the calcium hardness level of your spa water can help prevent the addition of even more chemicals to help balance the water, and help prevent costly repairs in the future.
Keeping calcium hardness in balance is one of three important water balancing steps. The other two are pH and total alkalinity. You should always make sure you have first balanced total alkalinity, then pH, and lastly calcium hardness when balancing your Hot Tub.
The ideal range for calcium hardness in Hot Tubs is 150-400 ppm (parts per million), so if you try to keep your calcium hardness in the midpoint between those two limits, then you should be fine.
