GreenClean Algaecide - Algae Killer for Immediate Algae Control

GreenClean is a non copper based granular algaecide that works quickly to control string algae and other types of pond algae. GreenClean is an algae killer that works on contact to kill algae and help keep ponds clean all year long.

GreenClean can be used for algae control in any water feature such as ponds, water gardens, ornamental waterfalls, fountains and birdbaths. It is a non-hazardous algae killer that is safe for fish, birds and pets once added to the water.

Once added to water the dry granules lose their toxicity. Be sure any loose granules that did not make it into the pond or water are collected and properly disposed of.

GreenClean Algaecide begins working to control algae within 60 seconds of application, with visual results in 24-48 hours. As with any algaecide application, we recommend a follow up dose of Pond Keeper beneficial bacteria to help degrade the resulting dead algae. Pond Keeper should not be added sooner than 48 hours after GreenClean or any other algaecide application.
