Fluval C2 Activated Carbon, Replacement Aquarium Filter Media, 3-Pack, 14011

These carbon pouches Fluval are an easy way to keep your aquarium water clean. They are the perfect size to fit in most filters and function right away to keep your water clear. It’s a good idea to give them a quick rinse under running water before using them; just to get rid of the fine charcoal dust. I usually replace these pouches when I notice the aquarium water isn’t as clear as usual; works both for fresh and saltwater setups. Great on there own but combine with filter floss and bio-media and you’re on your way to crystal clear water.Overall:+Provide Clarity+Easy to Use

It works good. It just takes time but once the tannins are gone, it stays gone.

Keeps my tank crystal clear

I use this in my Fluval canisters on multiple tanks, as an experiment I did a filter media rinse then added fresh carbon ( and Purigen) - and my measurements improved right away - this was prior to doing my weekly 20% water change. I usually do a rinse of the canister media every 6-8 weeks ( I don’t run a large fish load on any of my tanks) and at that point add new carbon pads and Purigen sachets. Going on four years and it’s working great.

Nice price instead of going to a pet store

Have always bought fluval products for my fluval filter for my turtle 55gal aquarium.

Love it. Working perfectly

Helps keep my aquarium crystal clear
