SKU: SGC20 Category:


GreenClean Granular Algaecide is a great product for controlling algae in water features! This EPA registered product provides extremely fast results in treating both green water and string algae. GreenClean can be used to bring algae problems under control as well as a preventative for future problems.

GreenClean works through oxidation which provides immediate control of algae. Dead matter floats to surface where it is removed by skimmer or net.

Ideal for use with bacterial treatments. Once GreenClean kills the algae, bacteria go to work cleaning up the remaining organic material. GreenClean will not harm bacteria.
