Metal halides are best if you want to have a reef tank. then there are t-5, then power compacts, then fluorecent, etc. If you were doing fish only I would perhaps only go with fluorecent. (much cheaper)much! :cheer: :cheer:
What about the T-8, and dont the bulbs of a T5 last much longer and save on power. I was just wondering in the process of redesigning and might as well do it all at the same time. As long as the T5 can support a few corals on a 90 gallon i think i would be happy on not spending big money on bulbs a couple times a year.
Thanks for the input
