Just had my 7200 litre Kio pond delivered today and am very impressed with it. The delivery man was very helpful and helped me to lift it over my outhouse as that was the only way to get it in to my back garden.
So a big thank you to him for all his help.
Would recommend Ponds 4 Fish for there help and service.

I had never created a pond before. But this makes it so straightforward. It looks great, and I added a solar fountain to keep the water oxygenated. Very pleased. Picture or video available if you want to see! It’s good enough to make me want to add another one to the garden – maybe two!
