Freshwater Salt System Cartridge 3 Pack

The Freshwater Salt System Cartridge 3 pack is designed for a freshwater salt cell type system, specifically the caldera brand tubs. It is a set of three replacement cartridges that are used within the system to help maintain the water quality in spas. The cartridges are essential for ensuring the proper functioning of the freshwater salt system, which helps to keep the water clean and safe for use by turning salt into chlorine by electrolysis. These special cells are specifically designed to turn salt into chlorine using rare metals to react with the salt with just the right amount of voltage.
