How to Apply

Ponds & Lakes: Treat floating or submerged algae mats evenly from the shoreline out. Spread 1.5 - 2.5 pounds per 500 square feet of the treatment area. If the majority of your pond is covered during hot weather or when treating heavy growth, it is important to treat no more than ¼ of your pond at a time and wait the full 14 days before re-applying. This helps lower the risk of fish loss during hot weather or when treating heavy growth. Heavy growth may require re-treatment.


After application, do not allow undiluted granules to remain in an unsupervised area where humans or animals are exposed.

Not recommended for Chara treatments. Can be used in ponds with carp.

AlgaeOff cannot be shipped to Alaska, Connecticut, Hawaii, Puerto Rico or Canada.

Product Notices:

Keep product away from children and pets when not in use. AlgaeOff becomes hazards to humans and domestic animals - if absorbed through the skin or swallowed.
