    It is good and works perfectly fine in my FX5. It is a bit expensive though! It comes in a nice box but I dont mind buying the foam pads in a cheap bag if this would lower its price. Im throwing the box in the trash anyways.

    These are really nice and well made pads! Im using them in my FX5 for a while now. I usually split each pad in half as for me it is working better this way. It polishes the water and keeps it clear. I use 2 half pads in the filter, every time I clean the filter, I rinse one half in the filter water to keep the beneficial bacteria and pressure wash the second half using the garden hose to keep it looks like new. I change the pad every other cleaning. The price is reasonable.

    Not as porous as 3rd party alternatives but I haven’t noticed any performance improvement over 3rd party alternatives. Pretty pricey but they last a long time with multiple cleanings.

    These work wonderfully in the Fluval FX5 - a long time ehiem fan for over 35 years Ive been using these filters for larger tanks (up to 300 gal.) in pairs and theyre incredibly effective especially for messy fish. Of course, nothing polishes the water like a Vortex Diatom Filter which can filter out debris and pathogens down to one micron in size but these are supplementary filters meant only to be used once in a while. These pads although not as effective will remove particles down to about 10 microns. I run four FX5s and replace these about every 60 days. Like the white foam which is for coarser debris its imperative to replace them or your GPH will suffer and the re direction of water flow not being able to pass through can result in ahigher degree of bypass - an inherant problem with the FX5s in general. These do keep your water on the pristine side and the value on Amazon is excellent.

    These work as described, but usually pad like these can be washed out and resused. Not the case with these, very thin and only lasted me a month. The white version of these are much better in my opinion.

    Theyre nice for what theyre intended to do - capture food/waste particles and clear up the water. The problem is that they tend to clog up fairly quickly. I run two Fluval Fx6 filters on my 240g tank with 2 pads in each filter - one in the top tray, one in the bottom along with the biofoam and bio ball media. The upper most pad will be the first to clog up and it only takes a couple of weeks. You can get by with rinsing them out for 2-3 uses but after that its usually time for a new one. Im considering using up the last of what I have and then just pull them completely. Pulling the Fx6 open every 2 weeks to clean the pads and clear the flow is a bit tedious but not horrible. Bottom line - good product but fairly high maintenance.

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.
