Their porous design supports biological filtration by fostering beneficial bacteria growth, ensuring cleaner, healthier aquarium water.

## Description

Fluval Foam provides mechanical straining of particulate waste. It prevents particulate waste from prematurely clogging other filter media in the Module Stack. Although the primary purpose of Fluval Foam is mechanical filtration, biological activity will eventually occur within its pore structure.

Review: Check to make sure it fits your canister filter - Make sure that this is for your correct filter. I also recommend using Fluval, haven't had as much luck with knock-offs. Always fits and always does it's job!
Review: I've been using these for years - I have a Fluval 304 filter on a 50-gallon freshwater aquarium, and I've been using these foam filters for years. I LOVE the Fluval filter... it's worked consistently and wonderfully for me for quite some time and I've not found any other filter that I've experienced or think would work as well. The Fluval 304 has 4 filtration stages, the first of which is these foam filter blocks. BEWARE... the are sold in packages of two, but the 304 (and 305) filters require FOUR of these blocks. In other words, if you want to completely replace the foam filtration stage, you have to get TWO packages. That being said, the filter works great for me and my aquarium needs only occasional maintenance. I know that there are knock-off products out there, and I've tried some in the past, but the quality of the material hasn't been the same in the ones I've tried. Since the key to making the Fluval filter work is to ensure that the water passes through each filtration stage, it's important that this foam filter block fit properly and maintain its shape. I've had other knock-off products that lose their shape, which disrupts the function of the filter. To me, it's worth it to spend a few bucks more and ensure that the filter works as intended.

### ⭐⭐⭐⭐⭐ An excellent filter.
*by T***E on June 7, 2014*

I own two very large, red-earred sliders, and out of all the pets I've owned, cleaning after them is a nightmare. I use a Fluval model 205 external filter, and these foam blocks fit well and do their job, though I need four of them at a time. Here on Amazon, they are dirt cheap in comparison to what big retail stores such as Petco would sell them. With the Fluval Foam Filter Block, your tank will stay clean for about a month before you have to swap foam blocks. I highly recommend buying them here instead at retail stores.
