Hello you guys, so my wife want me to build a waterfall for my to connect to the koi pond. I have no idea where to begin, so everybody have some idea about how to do the waterfall, I'll be really thank you very much. Here is the back of the koi pond, the square box is part of the water also. I was going to put my shower filter behind that square box, and then I put some water lily in that box, after I was hoping to build a little waterfall to connect to the pond. But as for now I can't think of what kind of waterfall should I build. Anybody got some kind of idea or some kind of drawing, I would love to see it. Thanks for now.
