  • Formulated for fast acting results, Pond Logic Algae Defense can be applied directly to algae and chara to treat both floating and bottom-forming algae.
  • 1 gallon bottle treats up to 8000 square feet
  • Algae Defense carries no water use restrictions, making it great for fresh water lakes, potable water reservoirs, and game fish ponds.
