FROG Serene Mineral Replacement Cartridge + 4 Bromine Cartridges for Hot Tubs

Introducing the FROG Serene replacement cartridges, previously known as Spa FROG. These cartridges are designed to provide you with weeks and weeks of amazing hot tub water. They are compatible with both the Floating or In-Line System.

The FROG Serene system offers a comprehensive sanitizing solution that effectively eliminates bacteria in two ways: through a low level of bromine and FROG Sanitizing Minerals. This dual approach ensures that your hot tub water is clean and safe, giving you peace of mind.

By incorporating FROG Sanitizing Minerals into your hot tub routine, you can reduce bromine usage by up to 50%. This bundle includes 4 Bromine cartridges, which will last for weeks, depending on the size of your hot tub and how frequently it is used. It is specifically designed for hot tubs with a capacity of up to 600 gallons.

In addition, this bundle also includes 1 FROG Sanitizing Mineral Cartridge, which has a lifespan of 4 months. These minerals not only eliminate bacteria but also help to condition the water, making it feel softer and more comfortable. They also work to absorb any excess acids in the water.

With these Prefilled Cartridges, there is no need to handle or measure bromine yourself. This means no mess, no guessing, and no stress. Simply insert the cartridges into your hot tub system and enjoy the benefits of clean and clear water without any hassle.
