FreshWater IQ is an in-line self-monitoring salt system that tells you what it needs to maintain clean, natural-feeling water, with less time and effort. Because we believe your hot tub should take care of you, not the other way around.

Made for Caldera® Spas, FreshWater IQ comes standard on all 2024 and newer Utopia® Series spas and is an available option on 2024 and newer Paradise® Series spas.

The Salt System automatically generates chlorine from salt to keep your spa water feeling naturally fresh and ready to enjoy.
