Control Algae and Nuisance Aquatic Plant Growth

Excessive aquatic plant and algae growth is one of the most frequent and frustrating problems encountered by lake and pond property owners throughout the country. Before conducting plant removal, aquatic herbicide or algecide treatments we strongly encourage our clients to indentify any issues that could be fueling the nuisance algae or aquatic plant growth. Many times, this involves preventing nutrient loading (both internal and external), reducing organic accumulation, limiting sunlight or even increasing the turnover dynamics of the pond. If your pond requires treatment, more than 3 - 4 times each season please call for other preventative maintenance options.

About the Algaecides and Aquatic Herbicides ABI Carries

Aquatic Biologists, Inc. offers an extensive variety of products, equipment, herbicides, and algaecides designed to treat and/or control nuisance aquatic plants and algae the average water property owner can apply themselves. In addition our applicators use professional grade products (not available through our online store) when conducting onsite control services.

Aquatic Biologists, Inc. carries only EPA registered herbicides and algaecides. On average, each of the products we carry has gone through 10 years of research to determine its toxicity level to humans, fish, wildlife, and the environment before being approved by the EPA. It is very important to only use products that are registered for use in ponds & lakes to control weeds and algae. Products that are not registered for aquatic use have been known to cause fish kills, disrupt the ecological balance of the water body, kill trees on the shoreline, trigger mutations to fish, amphibians, and/or other wildlife and may even have harmful effects on humans.

Chemical Application Best Practices

  • Always read and follow the label when applying product.
  • Identify the target nuisance plant or algae you wish to control.
  • Always read and follow the label when apply product.
  • Follow all application rates and dilution rates. Do not mix products together unless specified.
  • Check for any restrictions including; swimming, fishing, fish consumption, irrigation, animal watering, drinking, etc.
  • Follow all safety procedures listed on the label including wearing protective clothing.
  • Treat pond and lakes in sections, treating no more than 1/2 or a pond's surface at a time.
  • During hot weather or when treating heavy growth, treat no more than 1/3 of your pond at a time. This is exspecially true if you are not aerating your pond!
  • Wait 14 days before re-applying unless a different duration is stated on the label. This helps lower the risk of losing fish due to low oxygen during hor weather or when treating heavy gowth.
  • Once the algae or weeds have browned and died, use a rake to remove as much dead material as possible.
  • Apply benefical bacteria five days after treatment to accelerate the breakdown of dead plant material left behind that would otherwise contribute to the buildup of muck in your pond.
  • Use preventative maintenance products to reduce sunlight and/or nutrients.
