In previous years I treated the 1/2 acre pond with 1 gal. of Cutrine when I saw FA on more than half of the bottom in the shallows, roughly about every 6 weeks from spring through fall. This kept the pond very clean. My "before" pics are the worst it has ever been. I have no doubt that without the tilapia the pond would be completely covered with a near solid mat of FA by now. I would like to resume feeding soon, I'd hate to slow down the growth of the BG, so I am leaning toward treating the entire pond and seeing if the tilapia can maintain for the rest of the year.
