There is more information out there than you can imagine. Noted authors? Martin Moe Jr, Albert Thiel, Julian Sprung, John H. Tullock, just to name a few. Websites? I'll give you a few:
Aquarticles articles about fish and aquariums Thiel Book - Table of Contents Beginner Saltwater FAQ: Setup About Saltwater Aquariums - Reef Tanks REEF JANITORS FOR REEF AQUARIUMS
The about.com has hundreds of links all over their site...they even offer salt 101 for beginners...kind of an online 1 week class
good luck!
