Fluridone "Sonar" will work on the DW and WM, but not on the FA.
If Tilapia are legal, then I'd go that route. Stock them as soon as possible when the water temp is above 60°F.
Go
here to measure your pond.
If you can get Tilapia, I'd stock them at the rate of 50#-60# (or more) per surface acre. Yes, a little heavy, but with the nutrient load, you'll need more than usual to stay ahead of the green stuff that's growing. Remove as many as possible when they die off in the Fall to get out the nutrients that they stored as they ate the plants/algae. Mother Natures clean-up crew will do a good job too, but any help you can offer her will be a good thing.
Definately a nutrient problem, but other than bringing in equipment and digging out all the muck and accumulated nutrients, I think a heavy dose of Tilapia is the way to go.
