Our pond is three years old and has never really had a significant FA (green, strigy mats) bloom, until this spring. It is going wild and rapidly expanding on the water surface. I would appreciate a beginner's course on control. A few details: the pond is 0.6 acres, 11 feet deep at the deepest part, stocked with large mouth bass and blue gill, it is run off fed, it is in Western New York State. We have an aeration system as well. Any advise about treatment and prevention would be greatly appreciated.
