overflow and sump

ok so i made this overflow and sump....the overflow is a design i copied off a post here (a very nice one i might add) and the sump is relitivly small due the fact of lack of space under the tank... i have some filter material covering the return line to help filter out the bubbles.... and ther is my problem... there is a gazillion microbubbles clouding up my tank... i just put the skimmer in today and that isnt helping at all... here b some pics...

 

Is there some kind of media or baffle by the return pump before the water gets to it?

 

yea, got some of that blue fiber stuff covering the return

 

it has been cycleing for abot a week now... just to throw that out there...

 

And those are bubbles right? The water just isn't cloudy. If those are all bubbles the pump has to be pulling in air from somewhere. Is there a divider between the simmer and return pump?

 

yea theyr bubbles, there is a divider, its not much of one tho. u can kinda see it in the pic
