About the pond

We have some goldfish and some Coi in the pond. The wood posts on my side are going to come down soon, but I have to pound them in as far as possible first. I don't have a sledge...
The water runs through two pumps; one works the waterfall side and the other powers the fountain. The waterfall splashes against some rocks, then you see a stream of water flow down over the rocks and into the pond. The sound is as much fun as anything, but seeing the stream is pretty cool as well. I was able to snag many large rocks from the local creek that runs next to my neighbor's house. I was pleasantly surprised at how many smooth and richly colored rocks there were in there, and at no cost to me! If I felt like that creek was anything other than a toxic runoff stream, then I might not have taken them, but I don't think crayfish are dumb enough to live in that thing.
