The Caldera FreshWater® Salt System offers a simple, effective, and low-maintenance way to keep your hot tub water clean, clear, and comfortable. Instead of constantly adding chlorine or other sanitizers, the system uses a small titanium cartridge to generate natural chlorine from salt, providing continuous water sanitation. This results in softer, more natural-feeling water that’s gentle on the skin and eyes while reducing harsh chemical smells. It also helps extend the life of spa components by maintaining balanced water with fewer chemical fluctuations. Practically, the system saves time and effort — users only need to check the water weekly, change the cartridge roughly every four months, and top up salt as needed, making it an ideal choice for those who want consistently clean water with minimal upkeep.
