I have dabbled in the reef hobby for over a year now and currently after a successful move across washington state I am down to a 20 Gal nano. The dilemma is that as far as lighting goes I only have two regular flourescent hoods one has an actinic bulb, and the other is an 8000K bulb I believe. The only obstacle I have to overcome is lighting, I read the threads on here and I have no idea what anyone is talking about beyond PC's, and T5's. I really like metal halide lighting but am completely clueless as to what you need, and am deturred by the high maintenance costs of replacing the bulbs. I would love to get my hands on a T5' hood for my nano, also anyone who can dig up a good article on lighting specifically MH lighting I would really appreciate it. Please let me know where to look for a T5 hood preferrably a 24incher...any websites with good deals would be more than great help for a beginner in reef lighting...THANKS A LOT!!!
