I have my old Magnum 350 canister and wanted to set it up on 30g tank as mech/bio filter instead of the usual and recommended mech/chem. Thought I would fill the carbon container with bio balls, put the mech sleeve over it and let it work.
Just wanted to get your opinions on why it would not work...

It can work... the downside to the Magnum as a bio filter is the media chamber is small compared to other models. But since you are using it on a smaller tank the smaller capacity should be fine...

Don't like the bio wheels, they take space and too loud for my taste. I will go ahead and go with my original plan of adding bio media into the carbon container, was thinking of going with bio balls but now think maybe Matrix. Any suggestions on that?

I understand. Would you say that it would be adequate for a 30g tank? I mean surface area and not the gph of course.
