Discover the Caldera Spas™ FreshWater™ IQ Salt Water System — The Easiest, Cleanest Way to Enjoy Your Spa

When you step into your hot tub, you want crystal-clear water, silky smooth feel, and a relaxing experience without the hassle of constant maintenance. That’s exactly what the Caldera Spas™ FreshWater™ IQ Salt Water System delivers — a smart, self-monitoring water care solution that makes owning a hot tub easier and more enjoyable than ever.

What Is the FreshWater™ IQ Salt Water System?

FreshWater™ IQ is Caldera Spas™ most advanced water care technology yet. Built directly into select Caldera models, this smart salt water system automatically generates the perfect amount of chlorine from natural salt to keep your water fresh, clean, and safe — no guesswork, no daily manual dosing.

The system even monitors your water in real time and provides clear, simple instructions on your control panel whenever adjustments are needed. It’s like having a spa care expert on call 24/7.

Benefits of Salt Water for Your Hot Tub

Switching to a salt water system like FreshWater™ IQ comes with a long list of advantages:

1. Softer, Silkier Water

Salt water feels gentle on your skin, hair, and eyes. No more itchy dryness or chemical smell after soaking — just a smooth, spa-like experience.

2. Fewer Harsh Chemicals

Traditional spa care often involves multiple products and frequent chlorine or bromine shocks. Salt water systems create chlorine naturally from salt, meaning fewer chemical additives and less irritation.

3. Crystal-Clear, Clean Water

The FreshWater™ IQ system keeps water constantly sanitized and balanced, reducing cloudiness, algae growth, and bacteria build-up.

4. Lower Maintenance

With its automated chlorine generation and built-in monitoring, you’ll spend less time testing and treating your water — and more time enjoying it.

5. Longer Water Life

A properly maintained salt water spa can go up to 12 months before draining and refilling, compared to the typical 3–4 months for traditional systems. That’s less work, less water waste, and more savings.

Why Choose FreshWater™ IQ Over Other Systems?

While other salt water systems require more frequent manual testing, FreshWater™ IQ uses continuous monitoring to keep water perfectly balanced. If the system detects that your water needs attention, your spa will tell you exactly what to do — right from the touchscreen control panel!
