The salt system has been in development and lab testing for over three (3) years while internal and field beta testing has been in progress for the last two (2) years.
The results from the beta were very helpful in refining the installation and operation of the system and the feedback was very positive with users indicating that their spa water was much softer (less irritating) and the system was easy to use which resulted in them using their spa even more than with their previous water care system.
