I can only tell you what works for me. I set mine on the bottom in the deepest water, but only run it at night. However, I am also running in a substantial amount of ground water. (about 41 gpms in my 1/10th acre pond.) If you are not doing so then you may want to follow his advice. If you are not adding aerated groundwater I'm skeptical you will able to keep trout though the summer unless you have some special conditions.


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