4 FROG Serene Bromine Replacement Cartridges for Hot Tubs

Introducing the FROG Serene Bromine Replacement Cartridges, specially designed for use in the FROG Serene Floating System or In-Line System along with the Mineral Cartridge (sold separately). With FROG Serene, you can effectively kill bacteria using a combination of low levels of bromine and FROG Sanitizing Minerals.

In contrast to chlorine, bromine dissolves slowly in hot water, making it easier to maintain and less prone to causing strong odors. It is also less affected by fluctuations in pH levels, resulting in a more efficient sanitizing process that requires less frequent monitoring.

The FROG Serene Fresh Mineral Water hot tub system utilizes Bromine and Mineral cartridges to combat bacteria, reduce bromine usage by up to 50%, and enhance the overall quality of your hot tub water. By reducing the amount of bromine needed, this system is gentler on the skin, hair, swimsuits, and the surfaces of your hot tub.

The FROG Sanitizing Minerals in the cartridges help to condition the water, giving it a soft feel, while also absorbing acid to assist in maintaining balanced pH levels. The Bromine Cartridge is adjustable to suit your spa's specific requirements and typically lasts between 2 to 4 weeks. It comes pre-filled for easy replacement and can be recycled once empty, contributing to environmental sustainability. Experience the benefits of FROG Serene today and enjoy clearer, cleaner hot tub water with minimal effort.
