Three Innovative Technologies. One Seamless Experience.
FreshWater IQ blends three game-changing innovations, FreshWater Salt, Smart Monitoring and new Dosing Systems into one integrated solution.
The foundation of the system, this generates chlorine from salt using a replaceable titanium cartridge to keep spa water fresh, clear, and natural feeling.
Our latest innovation, this delivers accurate doses of pH Up, pH Down, and Phosphate Remover with a simple tap, using refillable cartridges tucked discreetly under the spa’s filter lid.
The brain behind the system, this checks pH, chlorine, and salt levels every hour, and displays updates and actionable recommendations on your screen.
Our new Caldera® Spas app helps you monitor, manage and balance your spa water anytime, from anywhere. With just a touch, you’ll enjoy added convenience and peace of mind, whether you’re at home or on the go.
FreshWater IQ (Salt System with Smart Monitoring and Dosing) is available on Utopia and Paradise Series spas only. The FreshWater IQ Salt System is available on Vacanza Series spas. FreshWater IQ is not available on Fantasy Series spas. Please refer to the compatibility chart below for details.
