This is a great book, because it doesn't simply repeat "conventional wisdom", or the same stuff that
is in every other book.
Sure, it reads like a science book.. but it's great because everything that Diana claims in the book
is supported by hard evidence/other studies.. So you can see the reason for everything.
Even if you don't know high school chemistry, she breaks it down to such an understandable
level, that it's easy to understand.. Plus, you can skip the chemical reaction formulas if you
wish and just take in the information.
The chapter on algae prevention/control alone is worth the price of the book.
There are no pictures, but you must keep in mind, the purpose of this book is to give information
on how to succeed with a "low tech" approach (no CO2 injection, expensive lights, etc).. The
high tech way works too (I've tried both approaches).. However, even high tech people can
benefit from the information in here.
This is simply the best aquarium book on plants.. period.
