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

These are my go to filter supplier for my Fluval canister filter. Keeps my fish happy and my wallet fatter

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.

The only way to buy them!!!

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

This is a piece of foam. There is absolutely no carbon inside it. Wash it, the water will run clear immediately. With a carbon infused sponge, water should have a light black tint. The original pad does exactly that.

My son manages a huge aquarium room. These were on his Christmas list. They were perfect.

These pads work great for our filter

These work great in my fluval -bought more than once
