Actually no one has mentioned that as a possibility, but I can see where it could be. We had some challenges with FA, but the coontail has made the water unnavigable in places; we just get large globs of coontail fouled in the weed less prop on the trolling motor. We're hoping the islands become more of a nutrient sink, then there's always the duckweed and water meal. Would you share what works well for you in coontail ; I doubt we'll ever get rid of it all.
