I would also love to hear what the experts have to say about "super cooling". My ponds here in MN average 4.5' with the deep spots 6.5'. For 8 years I have run two windmills on a 1 acre pond and for 3 years a solar powered on a 1/4 acre.
I have had one fish kill due to lack of aeration in the 1 acre pond but have never seen (or maybe don't know what to look for)the effects of "super cooling"
The windmills obviuosly run intermittently and the solar runs at 3-4hrs/day with an average of .75-1 cfm
I leave my stones in the same locations summer and winter
This is a very timley question for us MN people since winter is only a few weeks away
