Do you think there would there be sufficient surface for an effective culture?  All the containers would have to contain balls I would think.

What about buying some ceramic rings meants for a Rena Canister filter.

They are very effective. A little expensive, but you can fit ALOT more into the same space compared to Bio-balls.

They also have Bio-Max media (ceramic rings) that are meant for Aquaclears aswell.

I have to agree with Aiglos that Ceramic Rings work VERY well.

I really think that the ceramic works better for a canister filter than bio balls, the bio balls are bigger, taking much more space and not really giving more for bacteria, as for the ceramic rings, you could fill the bottom tray, and this would provide a lot more area for the bacteria to develop.

nice and porous too.

Ithink bioballs are primarily for wet-dry types of filters, such as a trickle filter in a sump.   For a completely submerged application like in your typical canister filter, I don't think they offer as much surface area per volume as a lot of other products like ceramic rings, etc.
