FROG Serene Mineral Replacement Cartridge for Hot Tubs up to 600 Gallons

About this item

• 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
• 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
• The FROG Serene Fresh Mineral Water hot tub system incorporates Bromine and Mineral Cartridges crafted to remove organic impurities, decrease bromine consumption by as much as 50%*, and enhance the overall quality of the hot tub water.
• For use in FROG Serene (formerly Spa FROG) Floating System or In-Line System with the Bromine Cartridge (sold separately); FROG Serene eliminates organic contaminants 2 ways with a low level of bromine and FROG Sanitizing Minerals
• 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
