Superior Algae and Bacteria Control and Prevention in Irrigation Water


Source water used for irrigation is often the root cause of severe algae and bacteria issues like clogged irrigation lines, drip tubes and emitters. These issues can negatively affect productivity by causing serious maintenance and safety concerns, and increasing the risk of pest, pathogenic fungi and plant diseases.

AGS’s revolutionary liquid copper-based algaecides, Pura-Fi 420 and Pura-Fi Pond, solve these issues by preventing algae and bacteria outbreaks in greenhouse ponds, tanks, wells, reservoirs, and water distribution systems. Our unique ionic cupric copper formula enhances and protects plant growth. It does not negatively affect plant nutrients applied through irrigation systems and has the additional benefit of keeping lines and filters free of biofilm, slime, and mineral scaling. Eliminating pathogens is as simple as adding the product in the recommended dose to a greenhouse water source.

Pura-Fi requires no costly capital investment and is simple to apply. Only small quantities are needed to provide long-term proactive and remedial control of algae and bacteria. Unlike competitors’ products, the copper ions remain biologically active, killing algae and bacteria until consumed by the target organism. This significantly extends the period between treatments.

Use Pura-Fi 420 or Pura-Fi Pond to:

  • Provide superior algae and bacteria control and prevention
  • Provide long-term, proactive and remedial control of algae and bacteria outbreaks
  • Extend time between treatment periods
  • Keep lines, filters and nozzles free of biofilm, slime and mineral scaling
  • Enhance and protect plant growth and nutrient absorption
  • Help reduce overall maintenance costs
