Maintain properly balanced spa water with Mineral Harmony Boost, a calcium hardness increaser specially designed for mineral-treated hot tubs and spas. Boost raises calcium hardness when levels are too low, helping bring your spa water back into the recommended range.
Calcium hardness is an important part of balanced spa water. When calcium levels are too low, the water can become corrosive and may contribute to damage to spa surfaces and equipment over time. Mineral Harmony Boost provides a simple way to correct low hardness and help protect your spa investment.
Mineral Harmony recommends maintaining calcium hardness between 150–400 ppm. By testing your water regularly and adding Boost when hardness is low, you can maintain better water balance while creating the proper conditions for your mineral water care system to perform effectively.
