Well I wish there was some data that I could help with. In our perch pond I have run one air station in 12 feet of water 24/7 this winter and it has been so cold that twice it has frozen right over the aerator.

I have also had my pump pumping from our spring fed creek at a rate of 2500 gallons per hour over the water fall all winter too. There is a solid 6"s of ice over the water fall but the water is running under the ice down into the pond. It then runs to the other end of the pond and out the over flow.

We have a solid 24"s of good black ice over the pond and 15"s of snow now on it as well.

Last year we has some pumpkin seed cross redear sun fish and they all died. A happy misfortune. The only reason we had these fish were because I didn't know about this site and going by what the fish supplier suggested.

If there is any help I can be let me know.

Cheers Don.
