A few years ago I suddenly become obsessed with building a reef aquarium. I didn't know much about it, and I still have a lot to learn. These pages document a work in progress, from the setup of my first tank to more or less the present time.
Here's a good book: The Reef Aquarium, Delbeek and Sprung. (Most aquarium books that I've seen (as with the rest of the products in the industry) are garbage. However, if you look, you can find high quality items among the trash.) This book is not cheap, but it's well worth it, if you're serious about your reef aquarium. I'll probably need to find an additional book on fishes.
Also, I've had a lot of help from a friend from CMU, Chris Paris. You can see his reef here.
