Marinium Black Crystal is a high quality activated carbon that will remove organic pollutants, toxic gases and heavy metals in marine and freshwater aquariums. It is produced from bituminous coal and has a microscopic pore volume ranging from 0.45 to 6.0 ml/cc, which allows it to absorb both large and small organic molecules. Since Marinium Black Crystal contains less than 0.2% of ash and does not leach phosphate and nitrate, it is suitable for delicate systems such as reef aquariums containing corals and clams or planted freshwater aquariums with discus and sensitive plants. Marinium Black crystal is pre washed and conveniently packed in a bag that is ready for instant use.



Activated carbon can be used on a temporary or on a regular basis depending on the desired effects. Regular use provides a constant high clarity and toxic free environment but aquarists may have to provide trace element supplementation. The 250 gram packet of activated carbon is sufficient for treating up to 100 gallons of water on a regular or temporary basis. However, the actual amount of activated carbon required for aquariums vary from system to system, depending on the types of organisms maintained, amount of pollutants being produced and the effectiveness of other filter components. Activated carbon is exhausted and will need a replacement when the water in the system develops a yellowish color.
