The FA has not come back in the big pond. Oddly enough, it appears to be the small ponds turn with the FA, but only minor amounts along the shoreline that I have been easily raking out the past week.

I did nothing chemically. Much of the dying plant matter along the shorelines seems to be gone.

I guess This may have been a case of new ponds which have only been full since last fall going through some growing pains?
