The Freshwater Ag+ Silver Ion Sanitizer by Hot Spring has a new look! Hot Spring has moved all their water care products to be called "Freshwater". It's the same great product-just a different box!
Please note, this is NOT the Freshwater Salt System Cartridge.
This classic sanitizer by Hot Spring continuously introduces silver ions into your spa water inhibiting bacteria growth. This sanitizer can be used for a replacement in Hot Spring, Tiger River, Hotspot, Solana and Limelight hot tubs. The sanitizer improves the performance of ozone and should be replaced every four months.
