Cutrine Plus Granular

Rapid sinking granules for targeted delivery to bottom-growing algae. Visible reduction of algae growth 1-2 days. Chelating agents prevent the precipitation of copper with carbonates and bicarbonates in the water for longer activity. Stays active in the water longer than copper sulfate. Ideal for algae in deeper waters or bottom growing algae- use Cutrine® Plus Algaecide (liquid) for algae on the surface or in the water column.
