Frog Serene Mineral Replacement Cartridges Hot Tubs Sanitizer in-line floating

For use in FROG Serene (formerly Spa FROG) Floating System or In-Line System with the Bromine Cartridge (sold separately); FROG Serene kills bacteria 2 ways with a low level of bromine and FROG Sanitizing Minerals
The FROG Serene Fresh Mineral Water hot tub system uses Bromine and Mineral Cartridges that destroy bacteria, reduce bromine use by up to 50%* and improve the overall quality of hot tub water
Unlike chlorine, bromine slowly dissolves in hot water so it’s easier to regulate, has far less odors and is less impacted by pH swings making sanitizing more effective. Say goodbye to constant monitoring
You use less bromine, making water easier on skin, hair, swimsuits, and your hot tub’s surfaces. FROG Sanitizing Minerals condition the water for softness and absorb acid to help keep pH balanced
Each Mineral Cartridge lasts four months or whenever the hot tub is drained and refilled. It’s prefilled, eliminates the work and guesswork, and makes replacement quick and easy.
