Zanyzap 6 Carbon Impregnated Foam Pads for Fluval FX4 / FX5 / FX6 Canister Filter

Works as well as my old system of charcoal in bags and takes like 99% less time to change the filter. Worth the higher cost to charcoal.

Just as good as Fluval brand, 6 for the price of 2 Fluval. Also a good fit in canister.

So far, so good. Working as expected. Has helped keep my tank clear.

Great filters fit my FX6 perfectly

Very happy with my order.

Works the same as factory fluval filters for a fraction of price.

Carbon is seldom needed. You are almost better without it. This a a great option for a FX 6 filter. Place it last in the bin, just to protect the impeller from possible debris from your media. Replace it one a month. Carbon depletes quickly in this scenario, the foam is just impregnated with carbon. The amount of carbon you actually need for a large tank 75 gallons + is quite a lot. This amount of carbon is just enough to possibly remove medicine after treatments and the more obvious benefit is better smelling tank. It is a great option to just protect your impeller. As for actually making your water clear the bigger the tank the more carbon and the dirtier the tank the more carbon. It works great for my purpose. Nothing works better than regular water changes, and keeping water parameters in check. I have a 150 gallon tank with a single FX6 and 30+ African Cichlids and still need to get more. For clearer water use filter floss and water changes not this.

Great item
