Yikes...I feel for you, 7mag. Some aeration and herbicide experts will address this shortly I'm sure. Seems you must have a heavy nutrient load to keep facing these issues despite the aeration and herbicide treatments. What's your fish population situation? If your pond was dormant for several years, you may be open to draining and dredging the pond and starting over. Certainly seems a cheaper and more permanent option than continually apply chemical treatments?

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
