FROG Serene Replacement Bromine Cartridge for Hot Tub FROG Serene Floating System (01-14-3824)

The FROG Serene Replacement Bromine Cartridge is the bromine refill for the FROG Serene Floating Sanitizing System for hot tubs. Each cartridge works alongside the FROG Serene Mineral Cartridge to sanitize hot tub water two ways, reducing total bromine use by up to 50 percent compared to bromine-only programs. Each bromine cartridge lasts two to four weeks depending on hot tub size, bather load, and water temperature. The prefilled cartridge drops directly into the FROG Serene floater with no measuring, no mixing, and no direct chemical contact. Less bromine means water is gentler on skin, hair, and hot tub surfaces. Sold as a single cartridge.
