Check out my build on my 165. Just finish a acrylic sump with 6 compartment. Intake, Refugium, skimmer 1, skimmer 2, dual PhosBan reactor & return. 46" x 22" x 16"

sphelps...I'm not planning to order the glass for the baffels until late next week, so no rush at all.

Grizz...Your sump is killer man, if I had an extra 4 feet of main tank I would be a third wheel taking your design. Building a new house this fall, so who know's...I might just get that big tank I want

You could adapt my design to fit your sump dimensions. Put your refugium first, skimmer section just big enough for the skimmer and make your return small as it really does not have to hold much water.

Split you sump 12" back - 6" front, but refugium 1st, then skimmer, bubble trap and then return.

I'm more of a big ugly stock trough person myself but Melev has a lot of sump designs and advice on his site here http://www.melevsreef.com/allmysumps.html just look down the left hand column for the different models.

OK here's the general layout done in CAD followed by the final product pictures. In the CAD drawing all features are not shown and I altered the final product slightly to accommodate for a higher flow rate. The basic dimensions are the same though. If you omit the water reservoir you'll end up with dimensions very close to what you're looking for (30x18x16). Also please note that this is purely for reference purposes only, not open to criticism and was designed for someone else. Your exact needs/wants will not necessarily match this exact model.

Wow nice job, how do you find your refugium works being after the skimmer? I have always read that the refugium should ALWAYS be before any skimmers.

You could put it anywhere and it would make little difference, if you were to justify either or I would think after makes more sense. The two main reasons for running a refugium in my mind is nutrient export and pod culturing. Since the nutrients targeted by a skimmer and a refugium are in different stages of the nitrogen cycle this would not effect position, but a skimmer after the refugium could reduce the pod flow to the display. I also don't like the idea of refugium being a garbage dump so closest to the end is a little better in that respect.

Some also prefer to have the refugium separate and not inline, I just build whatever people prefer, if they have no preference I usually go inline at the end for the reasons above and simplicity.
