My personal opinion on aeration reducing a muck layer is that it may not reduce it, but it will slow down the process that will make it thicker. Aerobic decomposition is always better than anerobic.
As far as adding bacteria I believe it's a waste of money. I too have yet to see an good studies that prove it is beneficial. There is bacteria already there. You just need to give it optimum conditions to multiply.
You also need to treat macrophytes and algae that are out of control to allow aeration and the bacteria that is there to do an optimum job. Otherwise they are just adding nutrients in a continuous cycle. I also have to wonder how many nutrients are being added on the lawns of the subdivision. I see some perfect golf club yards on local lakes and I know it's not natural.
