Spa Frog Mineral Cartridge Refill 2-Pack

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

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.
