Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants ~AMERICAN pondweed -- how do I kill it ?

Takoma - Is the plant growing only along the pond's perimeter; or is it completely covering the pond's surface? Also, does it have a flower/bloom of any type; if so, what color?
Based on the "similar to" photo in your initial post and the fact that most aquatic plants are green, I'd be curious to see an actual photo of the offending plant that occupies your pond.
