In case people want to see my 150 gallon tank setup. I've been 8+ years out of saltwater reefs and back in September 2011, I got back into the hobby. First with a 90 gallon and shortly upgraded to a 150 gal. It was all because I saw people with 120 gal tanks that had a 48"x24" footprint. I really liked the depth. Slideshow showing my tank build.

A bit overkill, but will simplify in a future round.

You can see my 2x4 wood stand with plywood siding. You can also see my DIY crawlspace floor supports to support the joists under my tank (150gal tank + 40gal sump=190 gallons) @ 8lbs/gal water = 1520lbs.

Sump will be a 40+ gallon tank split into 1) display refugium (18" wide x 5" deep x 15" high) to host microfauna 2) frag tank & remote deep sand bed (18" wide x 10" deep x 12" high) to avoid ugly frag racks in display tank & also provide some additional nitrate conversion 3) macroalgae (chaeto) growout section (18" wide x 5" deep x 12" high) to remove excess phosphates & nitrates 4) protein skimmer (older generation Euroreef model) 5) return pump It's set up so you can look at the sump and see the fuge & frag tank.
