DragonFish - yup those bubbles look really big, though you are getting foam. In the video I couldn't see the opposite side where the water is discharged. Is the output above water? If that elbow is submerged it will put backpressure on the output flow and increase the level inside the skimmer. I keep my output elbow sideways rather than facing down to prevent any backup. Also try lifting your skimmer an inch or two.
