You can greatly reduce the need for chlorine with the Copper Silver Ionization system installed. Only a small amount of an oxidizer will be required after a heavy bather load or a rainstorm.
The greatest benefit of the Copper Silver Ionization system is that the ions remain in the water providing a residual protection. They provide long-term, nontoxic purification and prevent against recontamination. Unlike other types of sanitizers, the copper and silver ions remain in the water until they flocculate, or form masses with algae and bacteria then become large enough to be removed by the filtering equipment. A simple test kit is included with the unit to maintain the proper ion level.
