Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants How long should it take?

Thanks for replying guys.
I didnt put very much in about 2 cups of concentrated stuff right next to a fountain so it would mix well and the water temp was about 60 F.
I did notice parts of some of the moss around the pond did turn a yucky brown but not much. It seams like im fertalizing cuz the more I take out the more it comes back the next day hahaha.
again thanks for all the help.
