Good filter for a fish bowl?

[new2saltyfish]

Making a 2ish gallon fish bowl into a nano reef and was wondering if anyone knew of any type of filtration that would be good for it. All i want to keep is some zoo's. Problem is it's a bowl shape, so a HOB filter isn't really an option. Maybe a small pump and put a type of filter cartridge inline?!? Any ideas?

I wouldn't bother filtering the water. Do a 1 gallon water change every week. Flow would be my concern.

Airstone driven carbon filter?

i was thinking an airstone except for the fact that it will just blow air in through a small filter and not suck water in and push out...unless i'm thinking about it the wrong way? I figured flow would be alright because almost any pump would give a good turn over rate on a bowl that small.

I think the airstone driven carbon filters do actually force water through the carbon. they sell them at petco cheap.

The airstone creates an upward current. Put it in a tube of some sort with carbon above or below the airstone and water will be drawn through the carbon.

Canister filter?

I like this one. I could probably hide everything in a piece of live rock to. Does anyone think this would be enough flow as well? Not sure what i could add to a bowl for flow.
