FROG Serene Bromine Cartridges for Hot Tub System with 50 Test Strips - 4 Pack

Maintain your hot tub effortlessly with FROG Serene Bromine Cartridges, designed for seamless integration with FROG Serene systems. These cartridges ensure optimal performance and water care.

The FROG Serene System combines Sanitizing Minerals with bromine to maintain clean water. This approach optimizes bromine use, making the water gentle on skin, swimsuits, and hot tub surfaces. Bromine dissolves slowly, making it easier to manage and less odorous, enhancing the hot tub experience.

Each cartridge lasts 2 to 4 weeks, reducing the need for frequent changes. Prefilled for easy installation, they are recyclable when empty. Pair with FROG Serene Mineral Cartridges (sold separately) for superior water quality and easy hot tub management.
