I put in aggressive aeration in our club pond 4 years ago. The depth increased 2.5 feet. The bacteria was recommended (by the person selling it) to eat up the mass of leaves that fall in it every year from the fully mature cottonwood trees that grow along much of the bank and in the water. There are some maples and willows, but about 10 big cottonwoods. .4 acre pond with about 35% of the bank surrounded by trees right on the edge and in the water.

Still the question remains, has a study been done?
