Put a koi pond in my Tulsa yard last spring and now I'm basically running a raccoon buffet
So last April I dug this 8 by 10 pond behind my garage in Tulsa and had to pick between a cheap liner from the hardware store or a proper 45 mil one for about $280, and I went with the cheap one to save money. Two months in, a raccoon figured out how to flip my pump cover off and had a $60 koi for dinner, and then the liner started leaking anyway. Now I'm out the fish plus a new liner, which is the exact thing my neighbor Dale warned me about. Anyone got a raccoon trick that doesn't involve a fence and a second mortgage?
