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.
Mineral Harmony LOWER will decrease the pH and alkalinity of spa water. The total alkalinity of spa water should be between 80 and 150 ppm (parts per million). The pH should be between 7.2 to 7.8. High pH can cause scaling and/or cloudy water. (1.25lb)
