    These are kinda hard to find so i have these saved and Ive bought a few times for my turtle tank. They are exactly what I need for her filter.

    Water flow is great again. Thanks for the new filter. I tried cleaning the old filter several times but still doesnt work good.

    I use this foam pad obviously in a fluval 3 filter. The filter is amazing, I have a turtle tank and it keeps the water crystal clean. Easy to clean and easy to replace dirty pads and such. Great product

    Does exactly what its supposed to do!

Fluval Poly/Carbon Cartridges features two sides for effective chemical filtration, the crucial second stage in the filtration process. The polyester filter pad side filters out fine debris and contaminants. The carbon side filters out harmful liquid substances, colorants and odors. The Fluval Poly/Carbon Cartridge works in part with the Fluval Filter Foam Pad to help keep your aquarium healthy and clean.
