Seachem Purigen is a superb filtration media made of premium synthetic adsorbent. The unique macro-porous synthetic polymer effectively removes soluble and insoluble impurities from the water up to 5 times faster than competing filter media.
This filter media has a "Thin Bio-Film" Open Pores design that allows flushing of old dead bacteria film, minimise clogging within the media and ensures beneficial bacteria grow quickly within the media to efficiently remove ammonia nitrites from water.
