The pond is performing nicely. I have 13 different goldfish in a 3' x 5' pond made from 4" x 4" pressure treated lumber and a pond liner. The pond has been up and running for several weeks now and the fish have grown quite a bit and seem happy. The bamboo fixture in the pics also the water feature, but I turned it off for the pics. There is no filtration system aside from the small black, plastic cube that came with the pump. Instead, I simply treat it like a large outdoor aquarium and siphon out and dirt and debris out of the pond and it seems to work well enough. Hopefully, the fishies will all make it through the winter. Although I live in Florida, so we don't really have winter :)
