Suspended floating particles such as algae, dirt, silt, fine sand too small to be removed by filtration, are clumped together by a unique ionic attraction that forms larger particles that are then easily trapped. Use Nutrafin Clear Fast for cloudy aquarium water as a result of tank disturbances, floating debris, aquarium maintenance, new gravel introduction, or suspended algae.
