Alysoun, this is not so... The history of copper use for algae control,
epizootic preventative and anti-fouling "paint" component is very long and
deep. I have access to some ten thousand references on the use of this
element... MANY concerning its economic use that touch on incidental exposure
to desireable freshwater vascular plants. This is the same stuff as "blue
stone" CuSO4-5(H20), used in potable and recreational waters all over the
planet. You may want to make a trip to a large (college) library to
investigate the latest info..
