SWC Xtreme 160 Protein Skimmer still breaking in? Need help.

[snow1]

I bought a SWC Xtreme 160 Protein Skimmer. I was told it would take around 4 days to break in and start skimming. It's been like 10+days now and it still is not skimming. The water or bubbles inside it no matter how I adjust it does not even reach the neck of the skimmer. It doesn't seem to be working very well. Any advice to get this skimmer to break in? Or is it broken?
