The three most popular reasons for using PAK®27 for selective control of blue-green algae are:

• Controlling off taste and odor
  Municipalities and other organizations responsible for public drinking water know how quickly and unpredictably blue-green algae can result in taste and odor complaints from their customers. (Read more about taste and odor problems.)

• Needing a cost effective solution
  Unlike some alternative treatment methods, only a low dosage of the concentrated PAK®27 granules is required. By using PAK®27, water treatment plants also experience
  • Reduced frequency of filter backflow, and
  • Reduced activated carbon usage in addressing taste and toxin issues.

• Wanting an environmentally safe solution
  PAK®27 is clearly the responsible choice, because it's a completely biodegradable solution. It is non-persistent in the water supply, and it is non-toxic to the ecosystem. Accordingly, it has received full EPA approval for use in ponds, lakes, drinking water reservoirs, and aquaculture. Please see our expanded label here. It is also NSF certified as an algaecide and an oxidant.

Other important reasons for using PAK®27 are associated with avoiding or reducing the toxins produced by blue-green algae that present risks to humans and animals. And of course, elimination of blue-green algae is also aesthetically important for lakes and ponds in residential areas and on golf courses—even if they are not designated as sources of potable water.
