Ask about FreshWater IQ water care

On compatible Caldera spas, FreshWater IQ combines salt-based water care with smart monitoring. The Salt System generates chlorine, while Smart Monitoring checks pH, chlorine and salt levels and shows guidance on the spa’s control panel.

  • Hourly checks help you keep track of water conditions.
  • Clear readings are available on your spa’s control panel.
  • Practical recommendations help you understand when adjustments are needed.

Ask us about FreshWater IQ availability for your chosen spa.
