i like the stand..pretty cool.
i'm betting you bought the coralife super skimmer 65. if so, return it and look into a reef octopus protein skimmer. they are better by far. i also suggest you purchase one rated for 2 x your tank volume, as manufacturers rate these things vaguely...they have no idea what bio load and maintenance schedule will be in place, and they seem to stretch the truth a bit about their products efficiency as well IMO
buy 50-75 pounds of live rock and toss it in the tank. let it cycle for a couple weeks(with the light off, unless you want algae blooms) then start testing the water for ammonia and nitrite, and nitrate. once there is no detectable ammonia or nitrite, the water is no longer toxic and you can slowly add livestock.
