I already have the system up and running, it's a 75 gallon reef tank, there's picutres in my gallery if you're interested. But as far as filters go I dont have much, basically it's just a lot of water circulation. I have 2 skimmers, a corallife needle wheel and some cheap one that i bought on ebay, an aquaclear hang on filter thats just for biological and carbon when i need it, a fluidized bed, and a magnum 350 which is currently for circulation only right now. All else is a chiller which has a pump for circulation, a main return pump (a Rio), 2 power sweeps inside the tank, and thats it. I know it's probably all wrong for a reef tank but it's going fine for now. I have a 3 inch sand bed and about 100 pounds of live rock (I need more, I'm working on it).
