Hi there! I have had a fish only 29 gallon set-up for a year now. I am wanting to try out a coral, but have NO idea what is the easiest to start with, what kind of stuff needs to go in the water.. and so on. I want the easiest to take care of, and doesn't require all sorts of crazy stuff. I just need to know about like, calcium and all that. Also, I bought a "Coral Sun" light from my LFS, is this enough for any type of coral?
