Residue-free, quick-acting hot tub & spa water treatment balancer. Used to increase calcium hardness levels in the water.
Helps to prevent erosion of pool surfaces and corrosion of metal surfaces.
The ideal calcium hardness range is 100-200 ppm.

Directions:

  • Frequently test hardness levels to maintain a range between 100-200 ppm.
  • When hardness decreases to below 100 ppm, raise hardness levels by 50 ppm by pouring 110ml of IPS Calcium Plus for every 10,000L of spa water.
  • Keep spa in operation while pouring the product
  • Allow 15 minutes before re-entering the hot tub.
