HT,
They really go after that stuff. I have 2 grass carp in a 3/4 acre pond that completely eradicated the pondweed. As I mentioned I'd actually prefer some weeds just under control weeds.
Like you I have "natural" nutrients from a cow operation. I was incorrectly advised herein that I should fertilize my pond in order to "shade out" the weeds with the plankton bloom. What a bad piece of advice! That is why every chance I get I try to caution about the use of fertilizer. Many on this forum do not agree with me...but like Fox News says...we report, you decide.
