The Pond Doctor - Duckweed Treatment

Pond Doctor Anti Duckweed tackles duckweed through its roots and leaves - the product works both above and below the surface with a two step application.

A two step process, part of the product is added to the water and the microscopic clay like substance is absorbed by the duckweeed blocking its ability to grow.  The spray application disteributes a UV blocker which stops the duckweed absorbing sunlight.
