Cutrine Plus Granular Algaecide delivers professional-grade control for stubborn bottom-dwelling algae, including Chara, Nitella, and filamentous species. Its fast-sinking granular formula reaches the pond bed directly, targeting algae at the source for visible results within 1–4 days. Unlike standard copper sulfate, chelated copper remains active in hard water, resisting binding to minerals and maintaining long-lasting effectiveness. Safe for ponds, lakes, irrigation, livestock watering, and recreation when applied as directed, Cutrine Plus Granular minimizes repeat treatments, saving time and effort. Perfect for small or medium ponds, it provides predictable, measurable results while protecting aquatic life and your property’s usability.
