Well water generally is not well
oxygenated since it is sequestured below ground and so doesn't get good gas
exchange, and is often quite saline, so if it were me, I'd run the water
over a waterfall or create a fountain that would agitate and add oxygen to
the water.
..... dont forget that bacteria in the earth use up the oxygen in the
water as it trickles down so all that is left is other dissolved
gases, particularly CO2. many wells contain bacteria make H2S, so the
oxygenator is a good idea. but all it needs to be is a pipe with lava
rock (IIRC) to tumble the water before it goes into the pond.
alternatively, a holding tank like a 100 gallon stock tank with a
couple air stones might do it. and the easiest is to spray the water
into the pond using a fine spray setting.
