Hagen Fluval Carbon Filter Media, 100 gram (3/pk nylon bags) Fluval Activated Carbon provides many benefits in both fresh and marine water. Besides providing a small sieve for mechanical trapping of organic wastes, carbon also removes liquid wastes from water. The high quality carbon provides a large porous area to trap minute particles. It has also been recently noted that carbon will adsorb a large percentage of many of the nutrients in plant fertilizer products. In general, carbon should be replaced on a monthly basis to ensure that active adsorption is maintained. Carbon should always be removed during medication. Carbon loses its activity without outward sign.
