[GSAS-Member] Full ecology cycle aquaria system

[dave@cheapfishstuff.com]

Ever since I saw a documentary on how they're using (or creating) wetlands
to greatly clean up treated sewage, I've been puzzling over whether it's
possible to set up a complete ecology cycle system that requires no water
changes.

Such a system would look something like, aquarium -> filtering -> heavily
planted tank, maybe like a marsh tank* (may need more than one stage) ->
back to aquarium.

The planted tank(s) would consume the nitrates and related fish-caused
nutrient concentrations, and return the water to fairly pristine state.

Has anyone here tackled such a system, or know of resources related to
building one?

(* sans mosquitoes... I hate mosquitoes...)
