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.
