Dan,
I have an aquarium at work that has been filterless for about 2 years, I
think. It started with an air-operated box filter, until I realized how
little it helped. It is a 40 long with about half land and half water.
Plants grow everywhere! The only fish are several Gambusia and there is no
circulation. Right now I have a duckweed outbreak, sometimes there's algae,
but it seems to be running pretty well overall.
