I have a windmill setup that went out on me and i got a gast compressor and 2 diffusers to replace the windmill. If you can get power to the pond i would recommend a compressor setup you will get alot more turn over with a compressor than a windmill and its also cheaper. I have a koender windmill and its very nice and i love the way it looks but if the wind aint blowing it aint pumping.
