Calmat will not drop the quantity of minerals; the benefit of Calmat is to keep those healthy minerals such as calcium and magnesium in the water. Basically, the Calmat function is to stop scaling on surfaces. Calmat modifies the crystallization of calcium and magnesium, so can no longer connect to the surfaces and it is removed by washing with water as a microscopic powder. Besides to remove the lime scale; Calmat generates a controlled electrophoresis process which produces a protective layer of metal carbonate, this layer protects against rust and corrosion.
