There are some pictures of the ball valve sump design in Richards thread here http://canreef.com/vbulletin/showthread.php?t=37356

Thanks. I see how it would work. I'm not sure how effective it would be at eliminating micro-bubbles, though. If the water is aerated in the skimmer chamber, that would be transmitted directly into the return, right? No chance for surface dissapation.
