There are also wind-powered aerators that work really well if you're in an area that would get enough wind. The windmill wouldn't need to be right next to the pond either, you can easily run a couple hundred feet of air tubing to the diffuser in the pond.
Keeping the snow cleared off some of the ice in winter can help keep O2 from dropping too low.
