The high performance filter medium is suitable for both freshwater and marine aquariums and all filter types. The biological filter medium sera spore Professional is the perfect addition to sera crystal clear Professional. Directions Add filter balls to the aquarium filter system. Wash the filter balls regularly and insert them back into the filter system. Repeat the washing process a few times to maximize their re-use.
