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.
Ask us about FreshWater IQ availability for your chosen spa.
Salt System included with Utopia: at Ultimate Hot Tubs, the FreshWater Salt System comes as standard with the Caldera Utopia range. For other compatible Caldera hot tubs it is available at extra cost. This offer does not apply to Fantasy spas or Endless Pools.
The Salt System and IQ Smart Monitoring are separate components. Ask us to confirm the monitoring, dosing or connected equipment supplied with your chosen spa.
