Bocomo thanks for the link. Interesting stuff.
I have seen folks trying not to mix all the bottom water in summer to try to leave a cold refuge. I am trying to understand if it would work the same way in the winter. If I keep the diffusers shallow will it leave bottom water unmixed??
Ah, I think I misread your original post. I think shallow water aeration is what most people do around here to do exactly what you describe. I'm curious to see what a real pro has to say on this.
