			 It is a strange skimmer.  I work at an Aquarium store and we use them on 2 of our tanks.  They are set up the exact same way, but one give bubbles and one doesn't?  Go figure.  We just added an air pump to the venturi....it works great.  I don't like using air pumps though...none of the staff can figure it out..
