<DIV>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.</DIV>

air<BR>compressor<BR>to use for a pond aeration system. Higher voltage DC<BR>preferred for<BR>direct PV module power. I'm not sure how to calculate the<BR>pressure and<BR>volume needed but a similar 120vac pump draws about 1200<BR>watts and<BR>delivers about 9 CFM. I assume that the same wattage DC<BR>motor would<BR>mean comparable air supply.
