A while ago I saw a really cool biomedia container for power filters somewhere on this forum. Of course I can't find it now. I'd like to add biomedia to my Penguin 350 filter, but I'm not so keen on filter bags. This contraption is a slotted plastic cartridge that pops open and allows you to fill it with any kind of media you like. Has anybody seen this thing???

I think you'll find what you're looking for here.

Oh yeah!! Excellent Bak2it, that is excatly what I was looking for! Thanks a bunch!

A pair of those media baskets came with my Emperor 400. They fit in front (as the water flows) of the regular cartridge.

I believe it would be an "E" cartrige from Marinel and for the emporer where the 350 uses a "C" cartridge. Im not sure if they are the same dimensions or not. I got a generic one from my LFS and it works fine but was made for the penguin.
