Eric,the pond is 1/2 acre and 1 year old. The muddy water is just starting to clear, I have approx. 12" visibility. The only fertilization would be runoff from the 13-13-13 fertilizer that I use on the grass.I am feeding the fish twice daily. I have an aeration system with 2 - 9.5" diffusers and a fountain. When I stocked the pond this past spring, I had a water sample tested. The alkalinity was 95, and the PH was 7.5. Earlier in the summer, I had a similiar situation, the only difference was it was green. It lasted a couple of weeks and it went away. This has been going on for a month now and doesn't seem to be getting any better. I purchased a gallon of algecide this weekend and I'm not sure whether or not to use it. My fish are really growing well and I don't want to mess anything up using the algecide.
