I have a WHisper filter right now, don'tknow which size as it looks old as dirt and has no indicator of which size it is as I got it used with my tank but I know it uses those Tetra biobags and I have a huge canister of activated carbon and a bunch of biobag refills that came with it. Its slow as molasses though and I am not sure if its the right sized filter for this size tank. Trying to speed up the water intake flow proves useless at this point it never changes.
Anyway, the question is, what other power filters (HOB) use biobags and/or activated carbon? I like the biowheel filters but they use those sealed cartridges which I am not too keen on. The Aquaclear price is right, but once again I have a huge can of carbon that would go to waste with either of these. Anyone know what GOOD HOB power filter uses biobags or at least loose carbon?

In terms of the Penguin, since the biowheel is where the largest colony of bacteria live, it shouldn't be an issue for changing out the sealed cartridges. I'm sure there is a way of using different media though, instead of replacing with the same cartidges.
