Cody:

I can't answer your questions, but I have this observation for you. The local lake has some public access areas around it. They are used for swimming. The first person brave enough to get in the water finds the areas have 6"+ of muck on the sand bottom. After about a month of people using it off and on, the area is back to a hard sand bottom. I can't for sure tell you that the muck was decomposed, or if it was just stirred up and floated off to the side. But, I do know that aerobic bacteria work a heck of a lot faser than anaerobic bacteria.
