So I have a 250 ballast laying around.....would like to run a 150 halide on the tank.......anyway I can make this work without blowing a bulb to pieces? I would like to use the same ballast.....but I think 550 watts of halide and VHO is a little much on my 29 gallon. Maybe not......but Im pretty sure it is. Built the new hood today, painting it tomorrow? Hopefully. Built it tall enough to support the halides and the VHO's if I want....Worst comes to worst....ill sell the halide ballast.....and keep the vho's
