Okay here's a Skimmer that I got in the bunch of goodies that I got for $20.00. I think I can use it in the reef somehow until I can get Angie to come over and help me look at some of the other items. I can use the pump that came with the Fision Nano Skimmer but I need to know how to get rid of the micro bubbles before they exit the system. If you look at the skimmer at the top there are the return holes. One all the way at the top and two at the base of the cone. Now how can I get rid of the bubbles and use this effectively. There is one more hole that I can plug because it looks like it's for an air line but becuase the pump is also an air pump I don't think I need it.
