Does your euroreef "gurgle"

[christyf5]

You could make the airline longer. I remember doing that on an old CPR bakpak skimmer I had and it worked like a charm. I had my euroreef hooked up to an ozonator so it has a super long line on it. I just realized that I hadn't removed it (not using ozone anymore) but no sucking sound (like I could hear it over the other various noises my tank makes anyways )
