When To Use Algae Defense®

Algae Defense® should be applied to target algae while it is active and growing. The active ingredients in Algae Defense® will be absorbed by the plant killing it entirely.

How To Use Algae Defense®

Mix the desired amount of Algae Defense® and pond water in accordance to label directions. Using a pressurized sprayer, like our Airmax® Specialty Tank Sprayer, spray the Algae Defense® mixture directly onto target algae. Overtime treated algae will begin to brown and die. Once it is completely dead, rake the dead algae away to prevent an accumulation of plant decay and pond muck.
