I don't understand how the aerator raises the temp. It raises the cool water which I thought would lower the temp.

I just put a pool pump in with the pipe 1' off the bottom and the output running over a plastic sled and splashing into the pond. I hope this helps for a day till we get back to 80's. Looks like I only have two trout left.

Now today I just happened to look down at the pond and a snapper about 12" was walking into the pond.

I'm still looking into aeration but not sure what to get yet. Some look to big others to small.
