CanyonCreek,

I run a diffuser at night in my trout pond and even at night on the hottest days of the summers (highs in the 90's) and most of my water column from top to bottom except for the top few inches stays right at about 60 F.

However this pond is small at only 1/10th acre 59 X 88 feet with steep sides, and I run in 51.6 F. degree well water at 45 gpm 24/7 in the summer.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
