It is simple, cheap, and easy to clean.
Basic details are water tank made from an old rubbish bin cut down. pump is just a small circulation pump for a fish tank. Square dish for the pond, cut a piece of plastic that sits on the white rings of plastic. I put a timer in so that it only runs a few times a day. It keeps real clean and the Fids seem to like it.
There's a couple of bids on You Tube showing them enjoying it.
