Above-ground Koi Pond
Above Ground Koi Pond
Picture of an above-ground koi pond with a viewing window for the fish.
After some research I think I have found the secret to building this awesome above-ground pond. At first I was concerned about the difficulty of building the brick wall with the viewing window and having it actually hold water with no leaking.
Then I found these fiberglass tanks from Aquatic Ecosystems.
These come in several sizes and have the viewing window built in. You could easily put the brick wall around the tank to dress it up like the picture.
I now have one planned for my back patio.
