I'd recommend an emerged bog plant. The leaves growing out of the water will provide some shade, limiting the sunlight for the algae. Plus, because the plant is pulling CO2 out of the air, where it's much more available, instead of the water, it should be able to out compete the algae for all the other nutrients in the water.
