I'm wondering what people think about vertical circulation vs horizontal circulation. Vertical circulation via bottom diffusers vs horizontal circulation via a donut shape pond + a pump.

Vertical circulation seems like a must, as it seems like the only way to bring up bad water from the bottom of the pond.

Given that vertical circulation will create some "local horizontal circulation" as the boil hits the surface, it feels like "global horizontal circulation" of water continuously circulating around the donut is unnecessary. I'm wondering what you all think about this?

Here is a sketch of the proposed pond to help you visualize the donut and how we could create horizontal circulation by pumping water across the "wall" in the river area.
