It is an easily recognizable tiny light green free-floating plant with 1 to 3 leaves 1/16 to 1/8 inch in length. A single root (or root-hair) protrudes from each leave. It tends to grow in dense colonies and in still water quickly covers the entire surface of the water depleting oxygen and cutting out the sunlight that submerged plants need for their growth. If left uncontrolled it suffocates and kills the pond.
IT Works, I know!
