KJ,
Is the weed really delicate and almost falls apart when you touch it ?
Our weeds look very similar and grows in huge masses then when it breaks the surface it starts to die off and decay but only the portion that breaks the surface.
I have found that if I rake it I can remove enough to make the pond visually appealing still but it leaves enough cover for the forage fish to hide. I personally like having them in the pond but they become a little unsightly when they break the surface. They provide excellent cover for forage fish and they will only grow until they run out of sufficient nutrients.
