Oops! Something went wrong. Please try again.
The AquaClear Mini Activated Carbon Filter Insert is a replacement filter insert that uses the power of activated carbon to help maintain a clean freshwater or saltwater tank. The premium research-grade carbon creates a large surface area that absorbs impurities and removes odors and discoloration for a clear aquarium. It’s designed as part of the AquaClear system that provides three types of filtration: mechanical, chemical and biological. In this unique system, only one component is changed at a time to protect the beneficial bacteria that’s usually thrown out with cartridge filtration systems. The AquaClear Mini Activated Carbon Filter Insert is an alternative chemical stage replacement that improves water clarity for a healthy, stress-free environment for your fish.

So much cheaper
By Smiley on Feb 19, 2021
I've been buying this item locally and was surprised how much cheaper it was here on Chewy so now I order here. Sadly all my fish froze in the Arctic weather we had in Texas, I tried all I could to keep them alive but without any source of heat it was a losing battle. I will continue to buy my supplies when I decide to start a new fish paradise...great deal and super fast shipping, I do recommend.

Keeps water clear and clean as advertised. Happy to see Chewy carrying this item at a much lower price than the local pet store.

Handy little carbon packs
By sfletch93 on Nov 3, 2016
These are a great value. I use them in my hang-on-back Fluval filter and in a Nuvo 10 saltwater aquarium. They do the job!
