I second or third (whatever) the stand a-ok, that steel combo, with that design does result in a increase of shear force at the points where the legs attach, but the steel is what you have to worry about bending, and it won't. Not with that little of weight. Anyway a 2"x4" can hold somewhere around 1400 lbs before shearing, yes it deflects but that's adifferent story. Sorry for ranting TRZ.
What would i do for equipment????? Hmmmm???
Well, some dolphin pumps would fit the bill, depending on what over-turn rate you want for the tank. The sump is perfect, the bigger the better. Maybe add a 55g mangrove "fuge" later? I'd definitely go with a 400 watt Iwasaki with MV ballast every 2' w/ URI VHO actinics to accent. As for skimming, search for "myreef" in the search user category of this forum. I know people are tired of me saying this, but i think he should get our business. He does great work and i've heard very reasonable. If your a skilled wood worker, then build one yourself. If your not keen on myreef designs, or DIY, then shoot for Precision Marine or ETS. That is if your not happy with your current skimmer choice.
Oh, where did you get those powerheads? They look very similar to the Gemini's.
HTH and good luck with your future business endeavor,
