The reason I put the loop in the pond was because of cost and efficiency (a LOT smaller loop & beater heat transfer). It doesn�t change the temperature of the pond very much itself, but if I ran an aerator continuously during the summer or winter the 10 degree change that I�ve read would affect my loops heat transfer.
What I�m thinking is in the spring and fall we don�t use the system much. In fact we�ve just started using it regularly last week so we could run it continuous. Then in the summer we could set it up on a timer to run at night. I really don�t want to run it during the winter unless it�s an emergency, because we like to ice fish. I've also read that running am aerator during the winter can lower the water's temp to much which is also hard on fish.
Would a run schedule like this work or am I missing the most important times to run it?

The stocking of the LMB this early is recommendation of our fishery Aquatic Control. Should I stop the order? Our minnows are going great. We put in 1,000 and I think there are at least four different sizes now and their everywhere.
