I'm not sure there'd be much of a trick to it. I used to be using an old aquaclear 150 (without any filter foam or anything like that) over my 20g just for some wee extra circulation and surface agitation ... and it was just full of 'pods. So I would guess a 500 would serve quite well. Are you thinking about lighting it? If you have a canopy on your tank perhaps you can somehow mount a light to that, that would hang over the aquaclear and thus provide you a grow-out area for macroalgaes too if that's maybe what you're looking for.
