The Inland Seas Premium Pelletized Activated Carbon comes in a flow through bag with a zipper. This Activated Carbon is of the highest quality and will remove odors and discoloring compounds from the water. Carbon should be replaced every month (every two months at the most).

A perfect substitute for the carbon bags used in aquarium canister filters manufactured by Fluval, AquaTop, OASE, AquaEl & Aqueon.

Because these flow through bags have a zipper, they can be re-used. You can buy bulk activated carbon, such as the Inland Seas Premium Pelletized Activated Carbon, 8 lb, and replace the 8 ounces of carbon several times while re-using the flow through carbon bag.
