I don't want to belabor the obvious...but...I don't think anybody thinks the windmill aerator is superior to ANY electric aerator. The whole point is that you can have an aerator where you don't have electricity. We use our own products...we're down here in Texas. Our situation is such that we don't have electricity run to any of our tanks (but one). With the cost of putting in electric lines (and the unslightliness) there's just no competition with the windmill. Check us out Wildlife Ranch Supply or email us [email protected]
