Frog Spa filter cartridges for bromine

[paulitzlee]

I used to use the Frog Spa floater system.  It had one blue cartridge for minerals, and one yellow cartridge for bromine.

Now I want to use the in-filter cartridges, but haven't found the bromine in-filter cartridges online; only the mineral cartridges.

Is there such thing as a Frog Spa in-filter bromine cartridge?  If not, how do you use bromine with the Frog Spa in-filter system?

Just google it. They are all over the Internet or stop by your local dealer I'm sure they would appreciate the business
