NO, those bubbles are NOT good for your tank or fish, shut them off. They usually come with a little nob thing to block the aireration hole, use it. Have a couple of your powerheads point towards the top of the water to agitate the water surface for air exchange and if you have greasey film on top, that helps too. :happyfish
