SpaPure C002729-CS20B6 Hardness Increaser; 16 oz 

Low calcium hardness can corrode the heater and damage the spa surface, and also can contribute to excessive foaming. High calcium hardness can cause scale buildup and cloudy water. High water temperature of a spa makes it more difficult for calcium to stay in solution, so it is recommended to use Stain and Scale Preventer weekly to prevent scale buildup.

The SpaPure Hardness Increaser is a granular product that is designed to safely raise the calcium hardness levels in your spa water. Regular use of this product will stop and prevent the corrosion of your spa's surfaces. This product is compatible with all systems including bromine, chlorine, mineral sanitizers, and biguanid


  • Helps maintain Calcium Hardness levels between 150-300 ppm
  • Helps prevent foaming and equipment corrosion
  • Promotes better water balance
  • Compatible with all sanitizers
