Spa Frog Mineral Cartridge Emerald Caldera Marquis Saratoga 40028800

Spa Frog blue mineral cartridge as used in the Frog in-line mineral and chemical canisters and also the Frog floating systems.

The Frog bromine and mineral spa water purification system is easy to use.  This is for the mineral cartridge for Emerald Spas, Great Lakes spas and other brand hot tubs that use the Frog system.

Don't test the spa water right after hot tub use, because the sanitizer will be at its lowest level then.

These cartridges are easy to replace.  The mineral cartridge actually lasts 3-4 months, so change the mineral cartridge only when refilling the spa every 3 months or so.

The inline Spa Frog system is installed by many popular hot tub manufacturers including Emerald Spa, Caldera Spas, Great Lakes Spas, Leisure Bay Spas, Marquis Spas, Morgan Spa, Pacific Hot Tubs, Polynesian Spas, QCA Spas, Saratoga Spas and others.

Need Frog bromine test strips? We've got those too.

 Spa Frog has recently been rebranded as Frog Serene products.
