ok back on track, do you plan to have a canopy on this tank? whats your price range? MH would be a great option on a tank this big and prob most cost effective, a good quality reflector and good bulbs and of course ballast, T5 are great but as i have found out more yearly maintenance buying bulbs but color is great, and of course LED which will cost more upfront. just wondering why do you want to wait so long (2013) to move into a mixed tank???
