Nice! Why didn't you make the CO2 area taller? It would allow for a higher drop and more swirling of CO2.
I see that you chose to hinge the lid. I assume you have enough clearance above the sump for that? I guess you need that room anyway for maintenance of the sump...
Very nice work! I need to make sure I bookmark this thread for when I get around to making something like this...
