don't get the ACE confused with the words "no maintenance" or "no chemicals needed" you still need to properly balance your chemicals (CH,TA,pH) before the salt is added, and check and adjust(as needed of course) once a week, but the salesman you spoke with is also correct, if it is a very low use spa you can get away with ozone(standard on jetsetter), silver ion, MPS, chlorine as needed which works wonderful (most of my jetsetter owners tend to be low use so the majority is on that system)
the price is also very fair, not a steal, but your def. not overpaying
Okay, good to know, thanks.
