I have a pond on my horse obstacle course that is about 2 ft deep. I just got a windmill with an air pump for cheap and am looking for ideas how to use the air. Thinking of an airlift pipe but not sure how much height I can get. Any ideas would be helpful. I might try about a 1 1/2 " pipe with an air stone and try from there. It would be great if I could get a 2 ft lift above the water level.
