Application Instructions

- GreenClean Tablets works best for preventative control of algae. For maximum results, water should be free of established algae problems.
- Add GreenClean Tablets according to the recommended application rates. When using more than one scoop in an application, distribute the product evenly throughout the water body.
- Skim any dead algae and organic matter that rises to the water’s surface after treatment. Allowing dead organics to sink and decay will provide a food source and additional nutrients that stimulate algae re-growth and further blooms.

- Control is most easily achieved when algae are not yet well established. Regular maintenance applications will prevent algae from appearing.
- Apply GreenClean Tablets on a bi-weekly basis. Do not apply more than twice a month.
- Never apply at higher than recommended rates.
- GreenClean Tablets is a slow-release formula. Results will not be immediate, but will be prolonged.
- For flare-ups and spot treatments, use GreenClean Granular according to label directions. Wait at least 72 hours to apply GreenClean Granular before or after GreenClean Tablets application.
- GreenClean Tablet(s) can be applied to water features such as fountains and ornamental water features containing fish when used at listed rates.
