The Larger Pond
The pond is less than 2000 gallons and houses 6 medium size koi. The flat rock bottom left is hiding a skimmer for 700-3000 gallons, a bit smaller than I would have preferred. The pump inside the skimmer is attached to a hose that goes underground on the left side to the in-ground *bio-falls*, also much smaller than I would have liked, but it does look hugely better than what was there, an external box with multiple hoses going in and out and above and gravitating down. To the right and up is the spillway where water from the pond goes into the little pond when a small hose from the little pond sends water into the big one.
