Help-Water Blaster pump creating micro bubbles
 

A couple weeks ago my Rio return pump finally crapped out on me during a water change. I went and picked up a Water Blaster 2000 to replace it. It's a nice quite pump but I'm having a problem with micro bubbles. Does anyone have any tips or tricks to try and correct this?

There is either a small leak in some plumbing attach or a pump seal...or something stuck in the impeller of the pump itself.
