There is a reason CC farms and hatcheries use paddlewheel systems. They move a lot of air into the surface (top 2-3 feet) water quickly. They are not whole pond (all depths) systems. Each type of system has its pluses and minuses - learn them and use what meets your goals. If you are running at a high carrying capacity then you need emergency aeration - like a paddlewheel type system.

That was a VERY interesting read. Pretty much proves it IS more
efficient to aerate at night versus daytime. Also interesting that running diffusers in deeper water allows more of the O2 from the bubbles to be absorbed into the water. We hear so much "the bubbles don't provide the air, the atmosphere does". Lots of good stuff in there. I am going to have to read it again.
