FreshWater IQ System

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.

How It Works:
Salt System + Smart Monitoring System

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

The Smart Monitoring System automatically tests your water every hour and provides clear instructions when adjustments are needed for clean water.

Energy Efficiency

In addition to the energy saving features built into every Caldera spa, the Utopia series features a thermal isolated base pan that beautifully frames the bottom of the spa while minimizing ground contact and improving energy efficiency. The EnergyPro circulation pump in our Utopia Series spas saves you money by operating at a very low wattage to filter water. Heater use is reduced, as energy used to operate the pump is transferred back to the water as heat.

On/Ready Logo Light

Each Utopia model features an illuminated Caldera logo badge which lets you know at a glance when your water is at the set temperature. It also indicates if your spa needs maintenance, a filter change, or service.
