Aquarium Filter Activated Carbon Biological Filter Filtration for Fish Tank

Features: Activated carbon has a strong physical adsorption and chemisorptions role in the adsorption of certain organic compounds to achieve the removal efficiency, the use of this principle, can quickly and effectively remove harmful in the aquarium water quality substances, odor, heavy metals, purification and softening of the effectiveness of water quality, as well as pigments, etc., so that to obtain direct and rapid improvement in water quality. This activated carbon works faster, better, and longer than the rest. Eliminates foul odors, unsightly discoloration, and harmful organic substances. Heat-activated bituminous coal-based granules are specially sized and far more efficient than coconut, wood, or peat-based carbons. Usage: Wash the Carbon before use.
