Thanks for the quick replies. We had a lot of rain recently, and I my pond is now about half full, probably 4' of water over the mud. Concerning structure, I wasn't sure how to add structure that wouldn't sink into the deep mud. Perhaps I should wait until aeration to install structure? I have no idea what kind of fish population I have, but I do have a lot of small to VERY large frogs, as well as turtles of all sizes. I estimate at full pond I will have about 10 linear feet of good solid bottom under water before reaching the mud, so maybe I can place the structure between the shore and the mud, in that first 10'. I am not aware of anyone who does aeration in this area. Would it hurt if I installed a single 9" disc membrane aerator myself?
