Yeah that's what I was thinking but you would need one hell of an air pump. That tank looks 4 feet tall, that's a pressure of 4 feet of H20 the pump would have to overcome. And I think it would have to be more along the lines of a venturi as an air pump wouldn't last too long with the moisture and humidity it would be exposed to in this situation.
