Packaged as a 30-pound professional bag, it delivers 3.7% copper from mixed ethanolamine complexes designed to inhibit multiple algae types without forming insoluble copper precipitates. This product is intended for controlled, labeled applications to freshwater bodies; always read and follow the included label instructions for dosage, safety, and use restrictions.\n\n\u003ch3\u003eHow quickly will I see algae reduction after applying Cutrine-Plus?\u003c\/h3\u003e\n\u003cp\u003eMost users observe visible declines in surface algae and discoloration within one to two days after a properly dosed application.
