Activated Carbon In An Aquarium

Removes Bad Smells. Activated carbon in the aquarium can help remove phenols to rid your tank setup of bad odors or that dreaded "fishy" smell. Phenols are typically caused by the breakdown of live plants, fish poop, and uneaten food. Over time, phenols can build up to high levels and lead to lethargy in fish.
