Not a serious aquarist here, but I did a lot of research before getting my little 10 gallon tank at home set up and everything I've read says the oxygen introduced by air bubbles in the water doesn't really dilute in the water well (most of it just comes up the bubble and out into the open air). In theory, as long as there is a big enough hole for a modest amount of air to be exchanged with the surrounding environment you shouldn't need any extra equipment, as the surface of the water should continue to exchange oxygen and carbon dioxide just fine as long as there is enough oxygen present.
- wtracy 10y agoWhat really matters is the surface agitation. Bubblers will do that, but so will any pump as long as the outflow is directed toward the surface. A better idea, I feel, is to just keep a layer of air between the water surface and the cover. The key issue is that oxygen has trouble crossing the air/water boundary, so you want that to be as big as possible. Meanwhile, if you keep the air holes in the cover small enough, most of the humid air will be trapped inside, and you will minimize losses from evaporation.
