This is a 3 pack of Fluval C4 Zeo-Carb Aquarium Filter Insert Packs (14019) for the Fluval C4 Aquarium Filter System (14003). These Fluval Zeo-Carb filter packs contain a combination of activated carbon and ammonia remover used as the Stage 3 chemical filter media in the Fluval C4 Aquarium Power Filter System. The Fluval Zeo Carb is a substitute filter for both Fluval C4 Carbon Packs (14013) and Fluval C4 Ammonia Remover Packs (14016).
These Fluval Zeo-Carb filter replacements for the Fluval C4 Aquarium Filter absorb unwanted odors, discolorations, and impurities as well as prevent the build up of toxic ammonia in your aquarium. The activated carbon portion of these Zeo-Carb filters reduces the amount of particulate matter for a healthier and cleaner aquarium while also removing any remaining trace amounts of chlorine and improving water clarity. Working with the activated carbon portion of the Zeo Carb filter, the ammonia removal portion of Fluval Zeo-Carb filters help your aquatic pets to better thrive.
Fluval C4 Zeo-Carb packs gradually become inactive and should be replaced about twice a month to better maintain water quality in your aquarium. These Fluval Zeo-Carb replacement filter packs are also known by Hagen part number 14019. They are for freshwater aquariums only.
