Pond bio filters clean a pond they do not prevent pond algae forming to make
pond water green and murky. To create a crystal clear pond an Ultra Violet Light
is required ... often called an UV or UVC (Ultra Violet Clarifier or Sterilizer)
Tetra-Pond Biofilters Role In The Nitrogen Cycle
TetraPond biofilters remove toxic ammonia using its advanced Trickle Flow and
Bio RIng technologies. Beneficial bacteria that adhere to the Bio Rings, convert
ammonia first to nitrites, and then to nitrates which are then used by aquatic
plants as nutrients. The UV Clarifier works by using Ultra Violet light which
kills algae cells as they pass through the clarifier. The dead algae and other
contaminants are then removed by the biofilter.
