Books

I'd like to get some recommendations for good books about keeping salt-water aquariums.

I just received for my birthday: Reef Invertebrates - An Essential Guide to Selection, Care, and Compatibility. This book is great. It really goes through all of the potential non-fish occupants of a salt aquarium, both helpful and harmful and talks about what is needed to keep them. Given my limited knowledge of the subject, it seems very comprehensive and I've learned a lot already even in my cursory reading so far. The author is very practical and gives advice even for difficult species that are inappropriate for most hobbyists, along with lots of caveats and warnings of course. He also has a large section at the beginning about the ideas of living filtration and refugiums, which was very interesting to me coming from a freshwater background.

I also have: The Conscientious Marine Aquarist by Robert Fenner, as recommended by the guys at Southwest Reef. It has also been very interesting, although much more focused on the "normal" residents of an aquarium, the fish and corals.

So, what other books do you have and recommend? Make sure you check out the sister thread over in freshwater for recommendations that belong there.
