Pond Clear Packets are natural, beneficial bacteria designed to breakdown "muck", remove excess nutrients and eliminate noxious odors from farm ponds. Pond Clear Packets naturally improve a pond"s water clarity by attacking suspended organic waste and muck. Pond-Clear can breakdown up to 5 inches of "muck" per year! Nature"s Blue is formulated to give your pond a long lasting natural blue color. Nutri-Defense works by binding up excess nutrients, feeding Pond-Clear bacteria and polishing pond water. After Nutri-Defense has bound up the excess nutrients, the nutrients sink to the bottom, out of the water column.

Nutri-Defense allows you to "manage the nutrients" so you can manage water clarity.
