  • Thin Bio-Film Technology
  • Combination of vast surface area and open/interconnected pores allow a thin bio-film to develop.
  • This thin film allows bacteria to flourish because necessary nutrients are immediately available.
  • With the open pores, old dead bio-film is easily flushed from the media and will not plug the media.
  • Water flows through the media, not around as with other denser medias, thus utilizing the most surface area for beneficial bacterial growth
