>Who needs a pile of expensive books that could be better spent on corals
Welp, mebbe if you had bought some books you wouldn't need to buy corals so often.
I note that for all the whining about how wonderful the Internet is, there were no substantive answers to the original poster's question: "Does anyone know of a website that provides light & care specifications for different corals in degrees of difficulty."
There are no such websites that are even close to being comprehensive or accurate. On the other hand, there are several books that are very good at this, and some of them aren't even very expensive.
All this blather about tank care, filtration, yadda, yadda, doesn't have a thing to do with the original question, now does it? The Internet is a wonderful resource, but to think that it can totally replace good reference works is silly, imo. Heck, if people would buy and read those books we could cut the volume on these boards at least by half.
