Will do, good thinking.

You could buy Practical Fishkeeping. They do cover ponds and have lots
of information. If you have specific questions you are welcome to email
me.

Cool. Thanks Rodney.
I've actually found quite a few aquaintances also keep and show Koi, so
have plenty of un-tapped resources.

Also been pointed to http://www.koimag.co.uk/
which has quite a few usefull bits in their FAQ.
