Well, I am in the DA club as well!! My DO is very low and my lake needs aeration badly. It is basically just a leech farm right now.
Last winter one windmill was not able to keep a hole open in the ice for me. So this summer I have the diffusers set in the deepest water and this winter I am going to put the diffusers some what close together in shallow water and pray for a hole or two! I don't THINK I could super chill the lake, but I'm no expert.
I wonder if the fish would rather freeze to death or suffocate? lol
