Frog Serene Mineral Replacement Cartridges for Hot Tubs up to 600 gallons

The FROG Serene Fresh Mineral Water hot tub system employs Bromine and Mineral Cartridges to destroy bacteria, reduce bromine use by up to 50%*, and enhance the overall quality of hot tub water. Unlike chlorine, bromine gradually dissolves in hot water, making it easier to regulate, less odorous, and less affected by pH fluctuations, resulting in more effective sanitization.

With the FROG Serene system, you'll use less bromine, making the water gentler on your skin, hair, swimsuits, and the hot tub's surfaces. The FROG Sanitizing Minerals condition the water for softness and absorb acid, helping to maintain a balanced pH.

Each Mineral Cartridge is pre-filled, eliminating the need for guesswork and making replacement quick and easy. The cartridges last for four months or until the hot tub is drained and refilled, and they are recyclable when empty.

The FROG Serene system is designed for use in the FROG Serene (formerly Spa FROG) Floating System or In-Line System, with the Bromine Cartridge (sold separately). The system kills bacteria in two ways: with a low level of bromine and the FROG Sanitizing Minerals.

Say goodbye to constant monitoring and enjoy the benefits of a more balanced, softer, and more sanitary hot tub water experience. The FROG Serene Fresh Mineral Water system offers a convenient and effective solution for maintaining your hot tub's water quality.
