I am getting ready to put in aeration system as soon as electricity is available, so am no expert.

However, I do remember Bob Lusk looking at the long, narrow island in my pond and asking, "Do you plan on aerating?" Anything that cuts down on the interaction between wind and water increases the need for aeration.
