Is the pond ground water supplied ? What is the bottom like? I assume those are circulators running (how long have they been there ?). What is the alkalinity of the water? Often swamps and bogs are highly acidic and will not support plankton blooms which are visible. Karmex is not a good thing to use in/around a pond. It may kill all the surrounding trees.
