What a difference a year makes, huh? We must have started about the same time because I just realized that I bought my first saltwater fish a year ago today.
Your tank is looking great, I cannot believe how much coraline you have on the glass, mine is not nearly that much. What kind of lights are you using? I think I read somewhere that coraline does better with less light. I am seeing this in my FOWLR tank with only flourescent lighting, it has more coraline in it (although it is younger) than in my first tank with MH.
