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 our 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.
