I think you are all missing the real question here or maybe just the better approch to the question. The issue isn't size alone - even the biggest filter will not remove a host of biological wastes and the fish will die. Rather, one can add filters to do specific things - a canister to convert ammonia into nitrite, then nitrate; a algae scrubber to convert phosphates into algae (for mechanical removal); a nitrate bio-reactor to convert nitrate into nitrogen gas; and a reverse UGF to keep the substrate clear. Also, secondary systems like a UV light to sterilize the water or an air wand to increase surface exchange. These are what I use on a single 75 gal and I still must remove 10% of the tank water a day and at least 50% a week or I'll develop algae ... . Size isn't really the answer to the question but rather, how close to a closed system does one wish to approach? That answers the questions completely - when one can keep a closed system (except water loss) than one has enough filtration and any further is pointless.

A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

Not to change the topic or anything, but everytime I see that filter, I think of the below

Omg Cliff thank you for that blast from the past. I used to watch home improvement with my dad every week when I was a little kid. I just suddenly became eight years old again watching that.~Manna
