Ok, I just installed my new NW-150, so I'm not quite so embarrassed of my sump now :roll: . It's about a 15 gallon sump and a 5 gallon remote refugium under a 72 bowfront. I have the skimmer plumbed back to the return section (kind of like a recirculating sump). Also notice the bag of carbon under the baffel, and the custom stand for the 'fuge.
Well here is my first attempt at a DIY sump. I am a little scared that i made the skimmer section to small. It does fit but it is a little tight. The skimmer goes on the right and return pump in the middle.
