Pipe systems continued
On this page we bring together the various diagrams that we have already shown, and in this case we are using a sand filter, heater, and UV unit before returning to the pond via a venturi.

This website started with a booklet which I made up originally for the help of those members of the BKKS - South Wales Section who were intending to start building a koi pond, and as the website has expanded more information and articles from other people have been included. This is for general guidance only, and we do not take any responsibility for problems that might occur by following these ideas. It is important that you check out everything in your area, and check on local laws and rules that may apply.
