I fell in love with the idea of having a fish pond in my back yard. How ever, it was very pricy to let anyone else do it for me. So,I decided to it myself. Here is how to. 1. Select location. Not too sunny. Not close to tree that fall in the autumn 2. Choose size. I can assure you that you might think you don't want a big pond, but most people regret the small size and redo this. So choose your pond size carefully.
