This carbon comes in various shapes and sizes and not all AC is equal. The most common shapes are granules and pellets.

There are powder forms as well, but those are not used in aquariums.

Freshwater planted tank keepers that use fertilizers with their plants sometimes refrain from using AC because it is thought to remove the fertilizer from the water column.

I've used both pellets and granules and both work well. The pellets allow for better flow through the reactors but the granules supposedly have more surface area making them last longer. When comparing multiple brands of AC you'll want to compare weight for a given volume.

The lighter the AC, the more porous and the better it will be. The lighter acid washed carbons are more expensive too. There are some good videos on youtube that will show how effective one type or brand of AC is over another.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.
