Don't know which to go with, I would like to have most corals and anemones. I can get metal halides for 299.99 at my LFS
but I have a glass cover to my tank and I don't want my water boiling.. If I do get a MH
can I put just one fan pointing at my water to cool it down? My tank is a 37 gallon, 3 feet long and a foot deep, 20 inches high I think. Any suggestions?
