Rendezvous Liquid Calcium Hardness Up
Rendezvous Liquid Calcium Hardness Up raises the calcium levels and increases the water hardness in hot tubs and spas.
Areas with low levels of water hardness experience a much faster rate of corrosion on hot tub plumbing and equipment than areas with higher levels of water hardness.
Low hardness levels are also responsible for the etching and staining seen in spas made from plaster.
Liquid Calcium Hardness Up increases hardness levels and prevents plaster etching and the corrosion of equipment and plumbing systems as well. It is an easy-to-use liquid product and it is compatible with chlorine, bromine, ozone and mineral purification systems.
1. Determine amount to be added by using a hardness test kit.
2. Pour proper amount into spa or hot tub with equipment turned on.
3. Run filter for 1-2 hours.
4. Water may be retested in 20 minutes.
