sump problem

[G-Man]

I am having trouble with my sump. It is blowing what looks like tiny air bubbles out of the spraybar. I am using poly-fil as my pre filter on the drip plate. I even wrapped poly-fil around the mag 12 pumps prefilter and it didn't help. The pump is in plenty of water and the spraybar is fully submerger. Any suggestions?
Here is my sump set up.

add a bubble trap, make the water go over and under a wall in the sump before it gets to the pump. search bubble trap in sumps and you'll see what i mean.
