Even with the whole unit placed fully under the water and fully closed air line, air bubbles still are blowing into the water. These are very small bubbles. Much smaller than they normally occur when the air line stays open. Is it possible that the impel To continually create air bubbles, the air must be coming from somewhere. You must ensure the entire unit is placed under the water, if the air is entering the system from the input, it should slowly eliminate the problem as the bubbles break at the surface and have no way to be replaced. You might want to shut off the system for a few minutes to allow any air in the water to rise unhindered and break at the surface. Another possible place where air is entering is where the water is boiling at the surface. Although this is pretty desirable, it may mean you must move the power head away from the filter agitation source to allow the bubbles entering to break at the surface rather than get trapped by the Power Head input.
