I can't find the link for the thread but check out The Talking Reef Podcast episode 88 from 1/18/07 entitled DIYTubeFuge. It is basicly a low flow hang on back dark sump made from a 3x20 inch pvc pipe filled with rubble.

I not sure if that is what you are looking for but I'm thinking about giving it a try.

a MJ1200 I don't have a sump. So far the pump pushes the water good throug the 2 75' coils and I need to slow it down.
