Description
Precision Algae Control for Ponds & Lakes
Cutrine Plus Granular delivers a powerful 3.7 % chelated copper payload in clay granules that sink instantly, releasing copper right where bottom-growing algae thrive. The result: visible reduction in as little as 48 hours and season-long clarity with far fewer retreatments. Its hard-water-stable formula outperforms traditional copper sulfate while remaining non-corrosive to equipment and safe for wildlife.
