Owning a pond covered with green algae or duckweed is less appealing unless you have feathers and webbed feet. Since 2012, National Pond Service have been activity researching the development of a simple filter capable of reducing the nutrients that support the growth of green algae and duckweed (lemna sp.).
Benefits of Country Pond Filters:
- Easy to install in about one hour, no excavation needed.
- NO chemicals involved, all natural products.
- Cost effective
