Kent Marine Reef Carbon contains essential Activated Carbon for use in marine and freshwater aquariums. Contains a fine coal-based carbon to remove organic pollutants, stain, and entrained toxic gases.
Carbon naturally removes trace minerals from water. Even after it appears to be expired from adsorbing organics, it will continue to do so. For best results, use carbon filtration intermittently and regularly replenish trace minerals.
Renew aquarium trace minerals with KENT Marine Essential Elements, KENT Marine Discus Essential, KENT Marine Cichlid Essential or KENT Marine Coral-Vite.
