Okay, here is what I see, starting (thanks for posting!) with #1

#1 That incline angle is going to FORCE the incoming water+air (Lets call it "mulch") down into to the water. Now since the mulch is moving rapidly, it has to pass through air, which would lead one to think that the air in the H20 would be released... Nope, it's moving too fast. So now it passes through another barrier of resistence, the H20; which the red indicates a swirling that will happen b/c the surface of the still water is being penetrated by fast moving air/water, which will actually push down MORE air into the water.

#2 Now that the mulch has made it down further into the water, and has release some air, while pulling some down with it, now that incline (I assume it will be the same width of the tube diameter?) creates a flow bottle neck for the outlet going to X-location. When the mulch travels down the incline and past the "lip" of it, some of the water will again be moving very fast and some slower, which will create another looping, which again, will mulch up the remaining air that's along with it.

#3 Ah, the slower moving water+air will now be released on the other side of the incline? Argh... Since the incline is blocking half of the res, the suction side (outlet at buttom) will be pulling as much water down as possible, limited by the incline's distance from the tubing wall. So you will have a Suctioned side. Meaning that there is more restriction of flow on that side, so ANY water that comes past the incline will be sucked down FAST, now the air really has NO chance of escaping to the non inclined side.

#4 If you could change or play around with the incline's angle, that would reduce the swirling effect of the incoming water+air...


Lastly, if you could post some pics or an MS-Paint of your case and the obstructions that are in the way, I could get a better idea of what you could do to make an efficient res/trap.
