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.
