Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Stocking Grass Carp along with feed trained LMB

Can someone answer the GC / coontail question? I have a major coontail problem and am trying several different solutions with little success (e.g. aquatic herbicides, GC, etc...). My current crop of GC are small and may not be mature enough to make a difference with the coontail. What should my expectations be with GC helping to control the coontail?
