Mineral Harmony Boost 16oz. (Calcium Hardness Increaser)

$8.59 USD

Mineral treated spas require the regular testing and balancing of the water for the minerals to perform properly.  Mineral Harmony was developed exclusively for use with mineral treated spa water.

Water hardness describes the total amount of calcium in spa water. Mineral Harmony BOOST brings water hardness into the proper range. Low hardness can result in corrosion of equipment and spa surfaces. The ideal hardness level is 150- 400 (ppm) parts per million. (16oz)
