I am a beginner at this and I am setting up a reef tank. So far I have 8lbs of live rock, live sand, a few hermits and 2 snails. (The inverts are in there at the advice of the LFS to help start the cycling of the tank.)
They said I should get my light as soon as possible. Right now I have a compact florescent sitting on top of the tank to allow for some light. If I plan on having corals and inverts and maybe one or two fish, then what kind of lighting will I need? The one they were wanting to sell me is $130 and he said its good for most things I would want to keep.
I don't really know what I want to keep because I don't know whats out there and don't know anything's requirements. I have a 20L with a Millennium 3000 filter. So yea, if I wanted to keep corals, inverts, and one or two fish, what would be a good light to have? And I have no idea what those abreviations are that stand for the different kinds of coral, so if someone could explain those as well.
