IMO your best compressor for your pond configuration is a 1/4hp rotary vane. It will run for 5 hrs on one kilowatt of electricity - 110 volts. Look into the GAST 0523 models of compressor. It will make plenty of air volume to readily mix your pond in around 3-4 hrs with two 9" dia disk membrane diffusers placed in a PVC manifold in the deep part of your pond. The compressor is very easy to rebuild when necessary.
