The guy who lives on a lot next to mine is the local sheriff and he told me all of the land had belonged to his family for decades. He talked about fishing in the pond when he was a kid so it has been there for likely over 40+yrs. I guess the level of muck, considering the surrounding trees on 2 sides of the pond and that length of time isn't too bad actually.

It lays in a low area between a couple of rises in the land, I don't think aeration would hurt it. Do you know of a specific brand product of bacteria I could add in a multi application attempt to curb some of the muck issue?

I believed the bass were extremely healthy in their relative length to weight ratio, they certainly were not skinny fish. and seemed rather chunky to me.
