I have an almost identical sump/fuge. Do you find you get bursts of micro bubbles? I'm trying to figure out if it's because I don't have the bubble wall on the fuge side or b/c air builds up in the elbows in the return line...or who knows...

I was having a problem where I would get a burst of violent bubbles on the fuge side while at the same time the level would drop in the overflow and the durso would make a sucking sound. I read on the durso website that this was likely due to the outlet being too far underwater, so I cut the pipe so that it was right at the water level. This didn't solve my problem so I decided to try drilling the air hole in my durso one size bigger. This solved my problem, but then my outlet kept making a lot of noise, so I put a 45 degree elbow on it so the outlet was just below the surface. This solved my noise problem.

I still get a lot of bubbles, but not large bursts that make noise. The bubbles don't make it to my pump either, which is nice. I think it's because I don't have a ton of flow moving my sump (about 550 gph).
