Cutrine® Plus Algaecide and Herbicide effectively controls a broad range of algae, specifically surface filamentous and planktonic algae including: Cyanobacteria, Green algae, Golden algae and diatoms, Filamentous Green Algae and Chara and Nitella as well as the rooted aquatic plant, Hydrilla verticillata.

  • Visible reduction in algae growth 1 – 2 days after application
  • Double chelated formula prevents the precipitation of copper with carbonates and bicarbonates in the water
  • Works in ‘hard’ water
  • Ideal for algae on the surface or in the water column – use Cutrine® Plus Granular Algaecide for deeper waters or on bottom-growing algae
