Add a little calcium increaser regularly to protect your hot tub from corrosion caused by low calcium.

Water hardness describes the total amounts of calcium in water. Calcium Increaser is the convenient way to bring water hardness into the proper range. Low hardness could indicate improper water balance and could result in corrosion of equipment and spa surfaces.


  1. Test water hardness.
  2. If calcium level is too low, make sure the pump is running and add 8 oz. of Calcium Increaser per 500 gallons of hot tub water. This amount will raise the hardness of your water 20 ppm.
  3. Run pump continuously for 30 min. and retest water. If hardness is not in the proper range keep repeating step 2, waiting 30 min. and testing again between each application.
