Russ and Theo. You're both right on the money. My pond is closer to circular than anything else. It has a little character to it, but no sharp shoreline bends. My 8 gpm sweeper nozzle is about four feet from shore, angled parallel to the shoreline. It's making the water spin around the entire periphery. I didn't think the one nozzle could do the trick, but this pond has 150,000 gallons and on a calm morning you can see the little surface particulate working it's way around the entire edge.
I am actually hoping that my deeper water isn't turned over as frequently, leaving a cooler layer on the bottom but with enough circulation to not become anoxic.
