I do not remember every doing one, but I have been asked several times. I assume you want the maximum oxygen for the minimum energy? or do you want the pond to have some circulation to prevent freezing? I would think just pumping air to the bottom would be a low return, prehaps spraying the water in to the air through small nozzels? or circulating surface water down to the bottom? a skimmer and then a circulae pump? I wlll ask a friend who is in water conservation and relay. DT

Higher voltage DC preferred for direct PV module power. I'm not sure how to calculate the pressure and volume needed but a similar 120vac pump draws about 1200 watts and delivers about 9 CFM. I assume that the same wattage DC motor would mean comparable air supply. Any experiences out there?
