Hi all, I'm thinking if purchasing a windmill aerator for out 2 acre spring fed pond. I mostly want it to help with DO levels in the summer time. I've got a couple questions though.

1) Due to the remoteness of the pond an electric aerator is out of the question and and a solar aerator is too expensive. Because of this remoteness though the pond is pretty well surrounded with trees - the trees don't stop the wind but will they hinder the windmills ability to get a sufficient amount of power to create oxygen?

2) How tall should it be? I'm assuming that because of the trees I'd want to go with the tallest model they make - 24 feet.

3) Will it harm my trout? Should I be concerned about it causing cold water shock in the winter? Will it kick up too much toxic odors at first use?

Thanks,
Uncle Sean
