Bruce:

If you were as interested in Dentistry as you are in ponds, cavities and gingivitis(sp?) would be history. ;\)

This is one of those concepts that after it is thought of, seems so simple. Forced turnover via water flow under pressure (or apparently horizontal airflow). I've watched this about 10,000 times while filling watering troughs, and the idea never crossed the plane into the pond management area of my brain.

I'm assuming you see hope for cooler-than normal species from temperature averaging the water in the entire pond (top to bottom), with O2 levels also distributed fairly evenly top to bottom. Is this correct?
