Finally finished. It's take a few months, and generally a lot of work, but here's the final product. Worked out rather well timing wise in the end, it's my birthday present to everyone interested in aquaponics.

Please download it and I hope you get something out of it, I'm pretty sure that everyone will get at least something from it, even the most skilled and practised aquaponics people. Please pass the link on to anyone you like, this is free for anybody with the slightest interest in building a system from IBC's. Yes thats right, FREE, FREE, Free.... So spread it around...
It's 187 pages, and fairly heavy on the images in many areas, so it's a reasonably large file to download at 38MB.
