Query: absolutely a must read

This is a mandatory reading for all beginning and returning to the hobby (me) aquarists. There are lots of other books out there, but none will give you as much basic information and fundamentals that are right on the money. The way I see it, the other books will give you many ideas how to fail. I'm always comparing to the "bible" - David Boruchovitz's book and having tried some of the other ideas, the fundamentals in the "Simple Guide" will always come to rescue.
