Fertilizing will eliminate your FA problem, as long as it's not prevalent throughout the pond already. Initially it may grow more for a few days, but once the plankton bloom happens the sunlight stops penetrating down through the water and the FA dies off.
I'd say harvesting 30-40 pounds of bass per acre, per year, would be a good starting point, per Greg Grimes' recommendation in the thread I tried to link to above.
I would skip gizzard shad, as I've read that often they don't make much difference for the bass but do end up overrunning the pond. And they'll kill your bluegill growth because they eat plankton.
