    I was unaware of polishing water until I got my Fuval 206 canister filter. This is way too big for my canister (my bad) but I took scissors to it to make it fit. Water is very clear. The polisher does get mushy after a few months but no big deal to swap it out for a new one. Once this supply runs out I will look for the polisher specific to my Fuval 206! If none, it is no big deal to cut to shape.

    We love these for our FX6 filter. Have a cichlid tank with 30 fish and these filters are amazing!

    This oem replacement works like it should by removing the finer particulates the larger pads dont. I added 2 of these polishing pads and a bag of carbon/ammo chips to the bottom basket of my FX6 and the water is sparkling clear on my planted aquarium. Once the pad starts to fall apart when cleaning, its time to replace. I recommend that these pads are replaced at that time and avoid trying to get more life out of it by placing it above the newer pad as some aquarium forum posts suggest as it may clog the newer pad as it falls apart.

    Big difference. Cleared my fish tank. Dont have to rinse carbon pellets. Just add to filter.

    This pad got hammered in my FX4. I put it on the top instead of the bottom of my baskets. Like an Idiot i thought the flow went the other way. Did the same with the hoses at first....

    They do as described. The aquarium is crystal clear. Thanks so much.

Fluval Bio-Foam performs double duty as both an effective mechanical and biological media. It is specifically designed for use in Fluval FX4, FX5 and FX6 High Performance Canister Filters. Bio-Foam provides outstanding mechanical and biological filtration thanks to an intricate pore structure that offers a large surface area for nitrifying biological activity. In addition, it trap small particles that are not retained by the first stage of foam filtration.
