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.

The Mineral Harmony QUATRO Mineral Purifier works by utilizing the water flow of the filtration system.

Why use the QUATRO Mineral Purifier?

  • Quatro minerals reduce harsh odors and scum lines.
