Hey Bill. The pond is not yet built. I have a flat field of clay that holds water well (tested in a few spots). We dug a 70x70 foot pond a few years ago that we really enjoy. I’ve been working on a plan to expand the pond. Given that it is a dug out we have somewhat of a “blank canvas”, so I’m thinking about how we can get it just right.

I think you are right that only the top couple of feet will circulate. Given this I’m thinking we’ll need to do bottom aeration all around the donut as well. But once we add bottom aeration I’m not sure if we’ll get any benefit from having horizontal circulation as well.

What do you think Bill? Do you think bottom aeration is a must? If so, do you see any advantage to including horizontal circulation as well, especially as it pertains to water quality? Any thoughts from others are appreciated as well.

Ted
