GreenClean Granular Algaecide is ideal for controlling string algae and algae blooms in ponds, waterfalls, fountains and streams. It works through oxidation and breaking down the algae cells on contact. When used in a pond the dead matter floats to the surface where it is removed by a skimmer or a net.

  • Kills algae on contact with results visible in minutes
  • For use in ponds and water features containing live fish and plants
  • Effective, eco-friendly chemistry – no copper residue
  • Controls string algae in ponds, streams and waterfalls
  • An EPA registered algaecide

Directions for Use

  • Use 1/2 pound (1 cup) per 1000 gallons of water for existing problems. 
  • Use 1/4 pound (1/2 cup) per 1000 gallons of water as a maintenance dosage.
  • For large ponds apply as preventative at 16 to 50 lbs. per acre-foot or as treatment of existing problem at 50 to 180 lbs. per acre-foot. 
  • Best to apply early in the morning on a clear sunny day. 
  • Turn off circulation. Apply to affected areas, including waterfall and streams. Turn circulation back on after 10-20 minutes. 
  • Skimming/netting dead algae helps prevent further algae. 
  • Always read and follow label directions.

Pond Cleaning

Use GreenClean for spring or fall pond cleaning. First, drain pond (remove fish & plants), then apply GreenClean to all surfaces. Rinse with water after 10-20 minutes and drain. Finally, re-fill the pond, replacing fish and plants after de-chlorinating as appropriate.
* Application not approved in California.

Waterfall Treatment

Use GreenClean for stubborn string algae on waterfalls. Turn circulation off and apply GreenClean directly to the algae. Let the GreenClean sit for 15-20 minutes before restarting the system.

Spot Treatment

Use GreenClean directly over the infested area. Re-treatment is required when heavy growth occurs.

Treating Roofs & Hardscapes

Use GreenClean to kill and prevent algae and moss growing on roofs, walkways, and patios. GreenClean may either be spread over the surfaces as a granular application or diluted in water to be sprayed on the target area.
* Application not approved in California.
