Surface Skimmer Bouncing

I have a glass lily pipe set which includes a surface skimmer on the top. It is connected to my Oase BioMaster 600 External Aquarium Filter. I have a powerhead also running facing the surface just to get some good agitation in the 300 litre (65 gallons) tank. The problem I am having is I find the surface skimmer will often bounces dragging in air to the filter and just in general making some noise as it's doing so.

I haven't adjusted by rotating the bottom part of the lily pipe intake because I still want a good flow of water getting sucked in. I am wondering if anyone has had a similar instance with this? Maybe the surface agitation is just too much making it bounce.
