“We’ve had that windmill behind us for about 10 years now. It does a tremendous job of keeping the ice off in the winter and therefore assures that our fish will survive. One of the nice things about it is once you’ve paid for the windmill there are no operating costs – virtually it works for free. It does a great job of keeping the pond healthy and the fish happy, adding oxygen and degassing the pond.”
