FROG Serene Mineral Replacement Cartridge for Hot Tubs - Spa Sanitizer for Spas 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
• In contrast to chlorine, bromine dissolves gradually in warm water, which makes it simpler to manage. It produces significantly fewer odors and is less affected by fluctuations in pH, enhancing the effectiveness of sanitization. You can finally stop the need for constant supervision.
• 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
• 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 FROG Serene Fresh Mineral Water hot tub system uses Bromine and Mineral Cartridges designed to eliminates organic contaminants, reduce bromine use by up to 50%* and improve the overall quality of hot tub water
