Freshwater Salt System

The Hot Spring FreshWater Salt System uses natural salt to generate chlorine, keeping spa water clean, clear, and soft for up to a year between full water changes. Shop genuine replacement salt cartridges, controllers, housings, caps, and test strips, all OEM-quality and designed for Hot Spring and Caldera spas equipped with the system. Replacing your titanium cartridge on schedule keeps chlorine generation steady and prevents the cloudy water or chemical imbalances that come with an exhausted cartridge. Genuine parts also ensure a proper seal and accurate sensor readings throughout your system.
