1. Swimmers prefer the feel and taste of water treated by Copper Ionization over salt water pools by an overwhelming margin.

2. Copper Ionization systems work within a calcium hardness range of 200-2,000ppm. Because it converts calcium to bicarbonate, the Copper Ionization will eliminate and prevent calcium scaling on pool walls and rock features. Salt water pools do not control calcium scaling and will only work within a calcium range of 200-400 ppm.
