Not too much oxygen (anoxic) not too little (anaerobic). Then it can only process so much. A couple of fish, plenty of water changes, ok. But if you have an aquarium stocked like many people do, the typical amount of live rock ain't gunna cut it.
Of course, if you only have a few fish, & plenty of photosynthesising corals, should be no problem.
