DIY Carbon Media Reactor

[Nico the Reefer]

I was interested in running some carbon in my 30 gallon system, but I've read that using carbon in a media reactor uses the media much more efficiently as opposed to just placing the media in a filter bag. I was thinking about adding some carbon into an old DI cartridge, since it makes for a nice reactor size with all of the media removed. I would then have a pump pass water through the cartridge with media and foam sponges to hold it in place.

Would this idea work?
Any suggestions would be greatly appreciated.

It will work fine I think. I saw someone make one out of a Gatorade bottle once, so your way would be good.
