Review on 🐠 Enhance Aquarium Water Quality with Fluval Carbon Filter Media by Heather Anderson

Carbon is always handy if you have aquariums and the low price allowed me to stock up and have lots of extras. I added mine to my Fluval 13.5 EVO, I have an In-Tank Chamber 1 Add-On and it's stuck to the bottom, but my water has never been clearer. It also fits my Fluval C-4 HOB filter and is almost exactly the same replacement. Also washed super clean, I run the charcoal in the reactor and this stuff is a mess to flush, there was almost no mess in the Fluval packs.
