So, this year has been especially bad. Out back of my house, our HOA owns a pond. Its probably 1/4-1/2 acre, and fills with rain/drainage. In the spring and fall, and of course winter, there isn't much that grows, but in the summer, we get massive clusters of yellow/golden-brown/green algae. Its gotten to the point where the pond surface is probably 70-80% covered. After doing a little reading, its apparently caused by lots of fertilzer/lawn treatment chemicals, and little aeration. Anyone know what we might be able to do to treat it? Our HOA pays to stock the pond and keep fish in it, but its almost unusable. I've been told that water plants will help oxygenate the pond, but would that be a better solution, than say, a windmill aerator setup? If so what sort of plants?
