Super Bio Breathing Balls - 5L filter media

Super Bio Breathing Balls filter media are used by professional discus breeders because they provide the most efficient breakdown of ammonia and nitrite in the smallest possible space.
Super Bio Breathing Balls can be used in a separate basket of an external filter placed after mechanical filtration or in the cassette of an internal aquarium filter.
Super Bio breathing balls are spherical with a diameter of 20 mm and can therefore be packed as closely as possible without disturbing the free flow of water through the filter.
Super Bio Breathing Balls is a highly efficient filter media that provides crystal clear aquarium water and is equally suitable for both freshwater and saltwater aquariums.
