Would This Work?

Simply turning an aqueaon 30gal power filter into a fuge. Basically my idea is..

Filter pulls in water
Water goes through initial baffle into sponge which is sitting on top of another baffle
Live sand, small small pieces of crushed rubble caked in coraline + cheato algae
Pumped back into aquarium
=???

You'd want water flowing in at the same rate it gets pumped out, so overflow might be the only option as you can't guarantee that the filter will pump at the same speed as the pump itself.

So would it ultimately defeat the purpose of a fuge in general? Couldn't I use it for extra water motion and have the sponge collect bacteria, occasionally polish the water with carbon, as well as harvest some extra bacteria of individualized pieces of rock? I'm not so much looking to house inverts or anything, MAYBE cheato, I mean I would like to have some... but if it can act as any sort of awfully cheap fuge that would be good enough for me.

So long as nothing detrimental happens

Sorry, previous comment isn't very relevant actually, it's a HOTB filter, so pump water in and it overflows back into tank? That would work, and there isn't really any reason why you can't use it as a 'fuge if you set it up right (someone else can help better than me on this point).

Yup, it's a regular filter except I cut and shaped the media basket pieces. Two near the initial pump which goes into a sponge, one underneath that sponge which has minimal sand, coraline, and hopefully soon chaeto algae.

It's running on a 10g tank, so yeah.
