Hello everyone, I have been into aquariums ever since I can remember. At first with tropical fish when I was a little kid, then it turned into angels and Discus. After many many spawns of both types I made a very small pond where I kept some goldfish and two Koi wish outgrew the pond fairly quickly. Then I got into Reef aquariums with corals, invertebrates and fish. This interest in aquariums paid for my College education. Now I have a small Home Depot plastic "pond" but it is doing very well with some small Koi. I'm at the stage where I really want to keep learning more about ponds and I'm going to build a big one when I feel that with your help I can keep my Koi in good health as they are in my small pond.
