Water Hardness Increaser for Spas & Hot Tubs

HARDNESS INCREASER

What ever sanitizer you use, the Total Hardness should be tested on first filling your spa and thereafter at monthly intervals. As water evaporates from the spa the minerals get left behind and become more and more concentrated, consequently the hardness of the water in your tub will increase over time.

Always adjust the Total Alkalinity and the pH before the Hardness.
