CAL SALT

Cal Salt™ Filtration Sanitation System produces a pure form of chlorine by electrolysis of salt (NaCl) providing pure sanitized spa water. Once salt in the water is converted to chlorine, bacteria is killed and the chlorine converts back to salt, the process repeats. Importantly, the salt concentration used is very low (less than that in a human tear).
