Thanks for the guide, there's some good tips there. If anyone else is thinking of making a pond I'd highly recommend it, its very interesting to see how quickly it attracts all kinds of animals.
The magpies were there this morning taking turns to drink out of it and theres now at least six of those swimming beetles, from looking at pictures on the net I think they are probably water boatmen. There seem to be even more bats around at night and lots of tiny insects like spiders running around on the sides.
All in all it was well worth the days backbreaking labour it took to build it!
