Overview

• Medium size, high porosity filtration medium for use in ponds and large marine or freshwater aquariums.
• Provides huge amounts of aerobic and anaerobic surface area for efficient bacterial colonization.
• Provides over 7,500 square feet (700 square meters) of surface area per liter of medium.
• When properly colonized, and used as directed, it will reduce toxic ammonia, nitrites, and nitrates to near zero in ponds and aquariums.
• Also reduces phosphate significantly and dissolved organics.
• Works excellently as the only filtration medium for the aquarium or pond or may be employed in addition to other filtration media.
• Works well for tropical and cold water marine systems. Works well in fish only, FOWLR and reef systems. Also works well in all freshwater and brackish systems to provide primary or additional filtration.
