Perfect for Chemical Filtration:
Chemical filtration media encompasses a variety of materials that can remove one specific impurity, a variety, and everything in between. The chemical method of filtration removes dissolved particulates from the aquarium via activated carbons and resins. Chemical filtration media cause the dissolved matter to adhere to them. The two most popular forms of chemical media are activated carbon and resins.

More Info
Types of Chemical Media for use in Fine Mesh Media Bags:
Activated Carbon
Carbon is filled with microscopic pores that allow certain organic or inorganic materials to stick to them. New carbon works more efficiently than older carbon. When all of the pores are filled, the carbon is no longer effective and the filter begins to act as a biological filter.

Carbon removes many harmful elements from your aquarium, such as: copper, chlorine, dissolved proteins, and carbohydrates. It also removes sulfa drugs and antibiotics, so it should be removed when the aquarium is being treated, then replaced when treatment is completed to remove any leftover medications. Activated carbon can also make your aquarium clear by removing discolorants.

Ion Exchange Resins
Resins are less utilized than carbon, but are becoming more common. These work by attracting a specific molecule to adhere to them. Some attract ammonia or nitrate, and some remove dissolved organics. Ion exchange resins are also utilized in some carbon mixtures like Chemi-Pure and Bio Chem Zorb. The resins often strengthen the filtering ability of the carbon, as well as help biological activity by removing pollutants before they enter the nitrogen cycle. Used properly, chemical filtration can be one of the most useful tools of the aquarist.

Ratings & Reviews
Articles
Mechanical filtration can greatly improve the health of most aquariums, and is also important for the efficiency of your biological filtration. The process is simple: mechanical media strains solid debris.
Biological filtration is the action of bacteria breaking down dangerous ammonia, converting it to nitrite, and then converting nitrite to less toxic nitrate. This article discusses how the process works.
While most aquarists agree biological filtration is imperative for your aquarium's health, not all agree that mechanical and chemical filtration is absolutely necessary.
