I had all that. Started with a 1/2 55 gal plastic drum. Ended with about a 3 ft deep 7x4 pond. Had about 4 giant coy and had one maybe 6 years my buddy started me out with it. I had about 10 fish lots of plants I loved fooling with it. Came home one afternoon from work early and my big coy laying out of the pond with some marks on him, he was dead. I found out the next Saturday why my fish went missing that big bird from the river had found my pond and cleaned me out. So after all that I filled in the pond and that was that. Still have the waterfall I was using can't get rid of it yet.
