I received back the CAD drawing for it today.

Hopefully it will be here in about 6 weeks.
Acrylic tank size is 96L X 48W X 30H. 600 gallons.
Circulation planned is to use 4 1" SeaSwirls in each corner (holes in brace predrilled) powered by a couple of ReefFlo pumps on closed loops (intakes are 4 holes along bottom of back wall) The idea with the SeaSwirls is to keep the top water zone moving well.
For a sump return I am planning on about 3500gph, return location yet to be determined.
I'll be supplementing tank flow with some Vortechs. I plan on putting in a 4" DSB and see how far I can push circulation over top of the sandbed.
I already have a few Luminarc III 400W lamps. I'll start out by putting 2 over the tank over the access holes. I also ordered lexan lids for the openings. I'll see if I can get a PAR meter and see how much of a difference the lids make.
I don't plan on supplementing the lighting.
Who knows, maybe there will be some plasma lights sometime in the future!
This is going to be a fun winter!
