I've used copper sulfate in my pond in the past. It does take care of the algae but you really need to follow the directions.
Too much of that stuff can kill your fish.
I'd be interested in any research you do on a fountain/aerator. I've kicked that idea area too but never done anything.
Ted Lea at ForeverGreen is in your neck of the woods. He can share his expertise in aeration. I have no commercial interest, but have had him give me advise prior to purchasing my system. You could probably drive over to his place and see first hand how the systems work.
Good luck.
