When our water temp reached 75 ish the yellow perch really turn off the feed. I have turned our air stations to run only at night 7pm till 7am to help cool the pond. Our pond has more water deeper at or below 30"s then above 30"s. The temp the top 30"s gains in the day with out water circulation is easily removed with the cool nights air temp.

Cheers Don.
