It is a brand new book, online, and it is free.

It covers, coral diseases and bugs and how to deal with them, aiptasia, sand beds, feeding what, how often and when, phosphate reduction techniques (zeovit), and for experts only building a tank for octocorals (dendros, gorgonia, etcetera) and lots of other interesting stuff.
