Query: Don't bother buying this book.

I have read a lot of aquarium and plant books but this is an example of a poor book. It looks like the publishes went to the library and collected a bunch of ideas from other books and through them together. I can't say that they give any bad advice, except in my opinion they mislabled two plants. Plus, there is a lack of a coherent theme through the book. They combine a few ideas that IMHO don't work together (this is from personal experience). Also the section on water chemistry is confusing, and before I read the book I knew it flat. The pictures are okay except they are all stock photos and you will see them someplace else in other books. Don't waste you money on this book. I would give it zero stars if I could.
