I think I may have been misunderstood here. What I was trying to say was worry about plumbing, how to do water changes, and general set-up. I guess I should have been more clear. I definately agree with these guys that you need to know what you want before getting your lights or for that fact a skimmer. My main point was to start getting the basics down before you get into corals and there needs. Just to be clear I agree that you should know if you wnat softies, lps,sps before getting your lights or skimmer, or your return pump. Ok enough rambeling I hope this clears up what I was trying to say.
