FROG Serene Cartridge Kit for Hot Tubs up to 600 gallons

The FROG Serene (formerly Spa FROG) Cartridge Kit provides weeks of amazing hot tub water, suitable for use in the FROG Serene Floating System or In-Line System. FROG Serene is a complete sanitizing system that kills bacteria in two ways, using a low level of bromine and FROG Sanitizing Minerals, resulting in cleaner, clearer, and softer water that is easier to maintain.

The FROG Serene Fresh Mineral Water hot tub system utilizes Bromine and Mineral Cartridges to kill bacteria in two ways, reducing bromine use by up to 50%* and improving the overall quality of hot tub water. By using less bromine, the water becomes gentler on the skin, hair, swimsuits, and the hot tub's surfaces.

FROG Sanitizing Minerals condition the water for softness and absorb acid, helping to keep the pH balanced. This bundle includes one FROG Sanitizing Mineral Cartridge, which lasts for four months, and three FROG Serene Bromine Cartridges, each lasting up to four weeks, depending on the hot tub size and usage. The prefilled Cartridges eliminate the need for touching or measuring bromine, ensuring no mess, no guesswork, and no stress.
