Right now my 40 Breeder has a 6 bulb retro fit built into the canopy but the bulbs are not the greatest and they were bought used with the kit. So I was going to spend cash on 6 quality T5 HO bulbs but for the money I think I can get a MH retro kit and try my hand at Metal Halide.
Heat shouldnt be an issue because my tank is down in my basement and has a hard time right now keeping 78 with 400 watts of heater.
So need some advice on maybe wattage to be used and if I will need two fixtures or just one over 36" x 18" x 16".
Also if someone has suggestions on a nice reflector I should use or any other hardware I should look into when building it.
Thanks
