Hi. bought DD fish tank for goldfish.It came with pump/filter that is inside the tank at the top. sorry for being a bit basic but should the whole unit be under the water level(waves along the top and water clear) or does the top of the unit where the cable is, go above the water level so there are millions of little bubbles in the tank....
Thank you
Thank you
