This mineral replacement cartridge is for use in either the Spa Frog Floating Mineral System, or for users of the Spa Frog In-line System. This mineral cartridge is the factory-installed, OEM product in selected newer spa models including Emerald, Saratoga, Caldera, Marquis, Morgan, Watkins Hot Spot, Pacific Hot Tubs and Leisure Bay spas.
Spa Frog Mineral Cartridges have adjustable settings. Minerals used on the maximum setting (#6) last 4 months. For smaller spas, or low-usage spas, a lower setting of #4 can be used, although your bromine usage may increase.
Spa Frog Mineral Cartridges (Blue) are used with companion Frog Bromine Cartridges (Yellow), either in the Spa Frog Floating System, or the Spa Frog In-Line System. Replace after 4 months of use, the all-natural Spa Frog Mineral Cartridge is safe to place in your trash.
Activation of your Spa Frog Mineral Cartridge is done with chlorine, to initialize or 'set' the minerals. Add a small amount of chlorine spa shock, like Spa 56 when first replacing the mineral cartridge. Afterwards, your Spa Frog will maintain the perfect bromine and mineral levels.
