Received about 4 inches of ice formation on both ponds in NW Ohio before the snow hit so no cracking of ice here.

Installed an AirPod as a winter diffuser last June and wanted to test it. I lost about 3 PPM DO in two days after the snowfall and started this winter diffuser yesterday and took ice out of a shallow offset area about 20 ft diameter in about 12 hours(normally would not let the opening get this big). This was done with 8.8 cfm as I wanted to see how much this new style diffuser could take.(very impressed).. Had 4 other diffusers shut down.

In the 4/10 acre lower pond I switched the Windmill back to the diffusers from open vent and went from the Koender Airstone to the CoActive Airstation as the stone will take several days to get through 4 inches of ice and the CoActive will melt through sometime yet this AM. (good wind at present).

Last year we had ice on/off four different times and no winter aeration used at all.DO levels last year never got below 90% saturation and at times were as high as 105% At this pace it could be a long winter in Ohio.
