Spa Frog Floating Mineral Cart


FROG Serene works by killing bacteria in two ways with sanitizing minerals and a very low level of bromine

  • Replacement Mineral Cartridge for the FROG Serene Floating System

  • Unlike chlorine, bromine slowly dissolves in hot water so it’s easier to regulate

  • Bromine is less impacted by pH swings ensuring sanitizing effectiveness

  • Soft feeling water that’s easier on skin, swimsuits and spa surfaces
