Man getting that balance of control is crazy hard.
My main pond has never grown any weeds other than some rush we planted around the edge. Of course I did put 4 grass carp in the pond early on as "preventative" (3 acre pond) which may have been a mistake.
Then this RES/SMB pond, within a hundred yards of the main pond, got over run with bushy pond weed in its second - third year from being built. Just crazy different how the two ponds evolved. Same soil types and clay.
One difference is the RES/SMB pond is further from the house and gets more migratory bird traffic. I think that is what brought the bushy pond weed in, as my other ponds have zero.
