Spa Frog Serene Replacement Bromine Cartridge.
The FROG® Serene Bromine In-Line Sanitizer System keeps water clean and clear, while reducing bromine and chlorine use by up to 50%. The result is fresh mineral water that is cleaner, clearer, and softer than traditional water care methods.
Introducing the innovation of Time Released Bromine Technology – the Time Release Bromine that works together with FROG minerals in the easy to use Frog Inline System Floating.
Unlike chlorine, bromine slowly dissolves in hot water so it’s easier to regulate. Plus far less odors. Bromine is less impacted by pH swings ensuring sanitizing effectiveness.
NOTE: Replace cartridge every 2-4 weeks depending on use.
