Marine Pure Biofilter Media Block (8” x 8” x 4”)


Marine Pure bio-media is the most technically advanced bio-media available today, designed to be a substrate for bio-filtration, specifically targeting ammonia and nitrite removal, minimizing denitrification.


Marine Pure is the perfect place for beneficial bacteria to flourish in order to remove harmful fish wastes, eliminating ammonia and lower nitrates.  


Thin Bio-Film Technology

Combination of vast surface area and open/interconnected pores allow a thin bio-film todevelop. 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.
