Ammonia Remover is a highly porous filtration media, used for removal and control of nitrates and rids aquaria from ammonia in fresh and salt-water systems. The process is called Anaerobic De-Nitrification. It is suitable for use in all media filters. Under normal circumstances an active biological filter consumes ammonia, but a number of elements like overstocking, overfeeding, old filter media etc. could cause the ammonia levels to spike.
In severe ammonia or nitrate spikes, it is suggested to do a 20% water change in addition to adding more Ammonia Remover into your filter.
