Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants help(identify) help destroy!

I have a 3/4 acre pond I just stocked 4 grass carp 16 inch. however since the rains have been low the pond is low and the vegetation is outragous. I can not fish the pond, it has got too bad. MY PROBLEM, IS A PLANT SIMILAR TO HYDRILLA. i AM UNSURE OF THE NAMES OF THESE GUYS., bUT i NEED SOMETHING TO KILL IT. MAYBE DOCKWEED? IT IS NOT HYDRILLA, BUT IT RESEMBLES IT IN APPERANCE. THE GRASS CARP ARE GOOD AND ALL BUT THERE IS TOO MUCH FOR THEM TO HANDLE AND i DON`T WANT TOO MANY OF THEM. aND AS FAR AS ALGAE, IT IS NOT PRESENT , NOT YET. IS THERE ANY HELPFUL HINTS?

Look at this site and id the weed. It will also tell about controls by clicking on the weed. Good luck.
