The greatest benefit of copper or copper/silver ionization is that the ions remain in the water providing a residual protection. The provide long-term, nontoxic purification and prevent against recontamination. Unlike most of types of sanitizers, the copper and silver ions remain in the water until they flocculate, or form masses with the algae and bacteria and then become large enough to be removed by the filtering equipment. When the “used” copper and silver ions are removed, the microprocessor control box is always producing new ions to continuously sanitize the water...
