The main thing is to learn everything you can before buying all of your equipment and setting your tank up. You don't want to waste your money on buying junk that you'll end up replacing later. Some things, like a sump or changing out substrate, are really difficult or time consuming once everything is up and running. One thing that you'll learn is that it takes alot of time to get a reef tank fully grown out, especially if you start out with coral frags. Don't rush the initial setup process and before purchasing equipment and setting your tank up, post what you're thinking about getting and get some feedback.
