it (aka, RoundUp) can be used in aquaria so that would be my 2nd choice; they add so-called "inert" ingredients to it, some of them may be the source of the rumors as inert does NOT mean it is really inert
1st choice - call the Agr. Extension Office for your county - your tax $$ can be put to work for you and you might just have some horrible exotic alien weed infestation that they should know about - might also come out and do the dirty work for you
if the pond is too shallow, or you fertilize the lawn or fields around it then you are hosed - search on "eutrophication"
