Just found this thread, and I did this last nite. Took about 20 minutes to adjust my sump. Bought the plastic screen at Michael's craft in Beavercreek, back the the latch hook section, 59 cents each. Roughed them up with a small saw blade. Extended my current sump return to be a little higher, and attached a 1" diameter pipe with a slit in it. Attached the roughed up screens with zip ties. But, I have a few problems. 1), the lights scare me. They used to be above my refugium pointing down into the water, which is bad enough I guess, but now the water coming in is actually higher than the light. 2) I can't get light on both sides until I move my refugium for the new tank. 3) the lights aren't quite strong enough, although I'm not trying to go skimmerless, so I'm not sure the 1 watt per gallon rule really applys. 4) I can't get enough flow until I re-plumb for the new tank. The refugium is above tank and gravity feeds into the main, however if it flows to fast it splashes and gets bubbles. On the 180 build, the refugium will syphon into the main tank, so flow problem solved there.
I've been meaning to try this for a while, after getting my new protein skimmer (MDX250A), I can see why some folks say it pulls EVERYTHING out of the water, including the good stuff. The thing is a beast. Anyways, pics....
