Frog Serene Mineral Replacement Cartridge for Hot Tubs


  • 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 designed to 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
  • The Mineral Cartridge lasts four months or whenever the hot tub is drained and refilled. It’s prefilled, eliminating the work and guesswork, making replacement quick and easy, plus it’s recyclable when empty
