Nitrate Sponge is a granular zeolitic
medium which will foster anaerobic bacteria growth, and slowly reduce nitrate
levels in marine aquariums to promote better fish and invertebrate health.
Nitrate Sponge adsorbs ammonia from freshwater tanks or tap water.

Place the media in a large mesh (800 micron) bag in your filter where water will
flow through the media. Each treatment of Nitrate Sponge will reduce the
nitrates by 20 ppm. Change one half of the Nitrate Sponge every 3 to 6 months
depending on organic loads.
