Description

Low calcium hardness levels can be corrosive to hot tub and spas surfaces and equipment. The ideal range for calcium hardness in a hot tub or spa is between 150-250 ppm (parts per million). Use this product to raise your calcium hardness level if it drops below the suggested range.

Directions for Use:

  • Test spa/hot tub water for calcium hardness level.
  • Add required amount directly into spa/hot tub water with circulating pump on high speed.  Continue circulating water for at least 20 minutes.  Do not pre-dissolve.
  • Retest and adjust if needed.
