Bill C - 10-4. I understand now. Maybe part of the difference for me is how much ice can form over night between run times. I don't know. I do know it is happening regularly though and appears to have been the problem for this year and last year at least. Probably the problem with the Koenders windmill the whole time.

Canyon - Love the dynamite idea, haha!! Unfortunately that seems like that might kill the fish itself!

Nehunter - I HAVE thought about using water instead of air. For now, I think we possibly have the air method whipped though. We think the vent pipe has a VERY high probability of solving the dome issue. Combine that with suspending the diffusers over deep water just a few feet below the ice and it might be a one, two punch!
