sump design feedback

I'll see if I can get things out of the way for a pic. http://www.bostonreefers.org/forums...-(air-bubbles)-how-to-quiet&highlight=bubbles but I used this as my guide.... really great info and did it on both ends. I think you have enough room to not eliminate the fuge.

I built my sump exactly as you designed in the original post. I did split the drain into the skimmer and refugium sections though. I do not have an ato- I need to add approx 1gallon a day. I have no microbubble issues at all.
