I'm putting mine together right now.I bought some plexy brackets to hold the tubes together,sorta in a sandwich fashion.And,I had two pieces of plexy cut to sit on each end of the top of the tank.I'm just going to lay the bulbs(4) on top of the tank until ,maybe someday,I make a canopy.I'm glad I checked here about the ballast because I was trying to figure out where to put it.I did'nt know it was safe to just put it on the floor.
