    I love them, I always have them on hand for polishing water. I use them in sunsun 603b canister, and in cut to fitnAquaclear 50, 70 and 110 hob. Works perfect

    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.

    Ive used this pad in the bottom tray of my FX6 for awhile now with no issues. Seems to trap a lot of debris (a good thing) so you have to rinse it in tank water every once in awhile. It also definitely helps to reduce the smells associated with my african cichlid fish tank and canister filter.

    Fit perfectly in my fx4 and made it look like my fish we’re flying in the tank

    This is a great product. It fit just like the old one perfect and it seemed very sturdy. I can say that this is just as good or better than the original one. And it seems to be keeping my tank clean.

    Buy these not the white ones. The whites one get flat and clog up the canister, thus slowing Dow the out put of water back into the tank.

    I use these polishing pads in my Fluval FX6 (75 gallon tank) on a regular basis. My aquarium water is crystal clear because of these pads. I change the pad every 30 days. By the 30th day the pad is black and about to fall apart. Ive noticed some green algae on the pad so I think it is blocking some algae from being pumped back into the tank. Never had any problems with these polishing pads and Ive been using them for 2 years now. They fit in my Fluval FX6 perfectly and they do what theyre advertised to do! Perfect! If this review was helpful in any way, please let me know by clicking on helpful. Thank you 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.
