Are you wanting the aeration because of the vegetation issues you're seeing? I'm not sure that aeration will help in this regard?
Yes and no. I want to get rid of some of the algae but the grass is a whole other issue. The pond fills from the side where the silt is slowly filling and making it more shallow. So I may just need to dig some of that grass out. It needs to be aerated either way.
suggestions other than herbicide.
