FROG® Serene™ Replacement Bromine Cartridge for Hot Tubs – Prefilled 1 Pack
FROG® Serene™ Replacement Bromine Cartridge for Hot Tubs – Prefilled 1 Pack
The FROG® Serene™ Replacement Bromine Cartridge is a prefilled, drop-in sanitizing solution that works seamlessly with your FROG® Serene™ Floating System. Unlike traditional bromine tablets or granules that require constant monitoring and manual dosing, this innovative cartridge releases a controlled amount of bromine automatically, maintaining optimal sanitizer levels without the guesswork.
Each cartridge is pre-measured and sealed, eliminating the need to handle harsh chemicals directly. Simply replace the spent cartridge with a fresh one every 2-4 weeks (depending on hot tub usage), and enjoy consistently clean, safe water.
