About this item

• 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
• Designed for the FROG Serene Floating System or In-Line System that uses a separate Mineral Cartridge; FROG Serene effectively removes organic impurities through two methods by utilizing a minimal quantity of bromine in conjunction with FROG Sanitizing Minerals.
• Each Bromine Cartridge can be dialed in to meet your spa’s precise needs and is designed to last 2-4 weeks per Cartridge. It’s prefilled, making replacement quick and easy, plus it’s recyclable when empty
• 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 FROG Serene Fresh Mineral Water hot tub uses Bromine and Mineral Cartridges that eliminates organic contaminants, reduce bromine use by up to 50%* and improve the overall quality of hot tub water
