What size is your tank.. From personal experience "I have the exact same hood" You can order Legs for the lights for 30.00 plus s/h or the hanging brackets for the same price.. From what I understand is the legs only fit 15.5" wide aquariums so it would not work on the standard 55gal.. The hood seems to be a pretty nice one so far and pretty well built from what I can tell.. I have had one Actinic bulb burn out on me that was only a month old... For mounting my hood that I got from them I used 2x2's and made a frame around the top of the tank for temp purposes and set the hood on top of it.. Made it a PITA to get into the tank but also put alot of the light into the tank without much going onto the outside..
HTH,
