FROG® Serene® Bromine Cartridge

FROG Serene Floating and In-Line Systems make sanitizing your hot tub easier than ever with consistent low levels of bromine, no chlorine odor, and reduced skin and eye irritation. The bromine and mineral cartridges snap into the reusable holder and can be easily replaced when needed.

The FROG Serene Bromine Cartridge works with the FROG Serene Mineral Cartridge to kill bacteria 2 ways. The system maintains clean, clear, and soft water that’s easier to care for with no measuring and no mess. Simply replace the mineral cartridge once every 4 months, and the bromine cartridge once every 2-4 weeks. The FROG Serene System uses up to 50%* less bromine than standard bromine spas.
