It's the best and only chelated copper I have ever and will ever buy.”

- Mark Roland, Professional Applicator, Limnology Information & Freshwater Ecology


A premium solution similar in nature to Cutrine® Plus algaecides but with the added benefit of an emulsified surfactant/penetrant combination. A highly effective control for coarse (thick cell-walled) filamentous algae, mucilaginous (colonial) planktonic algae, and Chara and copper-sensitive vascular aquatic plants. This product controls planktonic forms; green and golden algae and diatoms; filamentous forms, and benthic (bottom-growing) attached forms. It has also been proven effective in controlling the rooted aquatic plant, Hydrilla Verticillata, Egeria Densa and other copper-sensitive species. Waters treated with this product may be used for swimming, fishing, further potable water treatment, livestock watering or irrigating turf, ornamental plants or crops immediately after treatment.
