OK, I've been at it again...trying to put as much infromation at you finger tips as possible...so now if you need information on a particular subject...goto:

http://diyaquaponics.com/pdf.php

All you have to do is type in whatever you are looking for information on: Tilapia, Crayfish, Aquaponics etc. and poof, up pop a list of downloadable PDF files right at your finger tips.

Let me know what you think about it, helpful or what?
