Spa Frog blue mineral cartridge two-pack 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 item is a set of two of the 150g mineral cartridge refills as used in the in-line or floating FROG mineral system in hot tubs.

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.
