Important Note About Chemical Control of Aquatic Plants and Algae
Decomposition of dead plants killed by chemical treatment can cause a rapid decline in dissolved oxygen concentration in your lake or pond. This rapid oxygen depletion can kill fish and other resident aquatic organisms. If aquatic weeds or algae are abundant, it may be necessary to treat your lake or pond in sections, allowing plants in each section to decompose for 2-3 weeks before continuing treatment. Aeration, especially at night, will help prevent oxygen depletion.
