FROG® Serene™ Replacement Bromine Cartridge for Hot Tubs – Prefilled 1 Pack (Compatible with FROG® Serene™ Floating Sanitizing System)
FROG® Serene™ Replacement Bromine Cartridge for Hot Tubs – Prefilled 1 Pack (Compatible with FROG® Serene™ Floating Sanitizing System)
-
Designed specifically for the FROG® Serene™ spa system, this pre-filled bromine cartridge snaps into either the floating or in-line dispenser and begins sanitizing immediately.
-
The cartridge lasts roughly 2 to 4 weeks, depending on spa size, usage and dial setting — saving you time and effort compared to traditional bromine tabs.
-
When used together with the FROG® Sanitizing Minerals, overall bromine consumption can be reduced by up to 50%, while still providing effective sanitation for your hot tub water.
-
The low-bromine, mineral-enhanced chemistry helps water feel softer, reduces skin and swimsuit bleaching, and offers a clearer, more comfortable soak experience.
-
Easy to install: Remove the spent cartridge, insert the new one, set the dial, and you’re ready to go — no measuring, scooping or guess-work required.
-
Compatible with hot tubs and spas that feature the FROG® Serene™ Floating or In-Line delivery system (for units up to approximately 600 gallons). Verify compatibility with your spa manufacturer.
