Think about it. If the tank were air-tight, and you had an aerator pumping air in there, either the tank would explode, or the air would blow the lid off, or (most likely) the back-pressure would build up to be enough so no more bubbles would come out of the aerator.<br><b>References : </b><br> The lids aren’t air-tight, so enough air gets in (and out) to allow gas exchange at the surface of the water.

Just your plain hang-on filter does a good job at this, but if there's a spot in your aquarium that doesn't get much water flow, add a bubbler. Again, it's not the bubbles that add oxygen to the water, it's the ripples and disturbances the popping bubbles make at the water surface.<br><b>References : </b><br> The oxygen gets in and the CO2 gets out by disturbing the water surface in any way.
