Pond lover, that little pot on its side is in the front yard pond. There is a pump hooked up to the pot with a hose in the hole in the back of the pot. Then the water runs out of the pot and into the pond, just for a different look. I put rocks in the pot and you can move the rocks to change the sound and flow of the water. Those really big fish are close to 20 years old now, put them in that pond when they were real small, never moved them since, stayed outside every winter here in Canada, now they are very friendly cause I have never netted or moved them ever. They are like dogs and follow me around the pond. They are in the top pond, which is dug down and built up a foot or so above ground.
Look at the rocks, they are glued to the pond frame and then I stuffed moss in the cracks between the rocks. I used this foam stuff called GREAT GAP FILLER, got it at the hardware store. They sell stuff at the pond shop in town that is very much the same, but meant for waterfalls(29.99). I found it was way cheaper to get the stuff from the hardware store (9.99) Worked real good, get the foam stuff that expands greater than 1 inch.
