Carbon Aquarium Filter Media 500g with Bag

Activated carbon is carbon that has been treated in such a way that creates a large number of tiny pores, greatly increasing its surface area. This massive surface area allows it to adsorb a large volume of material, making it useful for removing pollutants from both air and water.

REMOVES CHLORINE AND CHLORAMINES

Carbon, or activated carbon, is used as a chemical filtration media. It helps to remove many organic and inorganic materials dissolved in tank water -- it keeps the aquarium water clear and removes odours. Activated carbon works by using absorption and adsorption. Absorption is the process by which pollutants are trapped in the pores of the carbon (you can think of this process as a molecular-sized mechanical filter). Adsorption occurs because the carbon has a large surface area (with all the pores) and, therefore, many chemical bonding sites. Adsorption is the process by which pollutants are chemically bonded to these sites and trapped by carbon.
