Up and running

This bio foam really helps keeping the filter running smoothly and trapping the gunk. You can soak it and clean it to reuse one or two more times before tossing

This bio foam really helps keeping the filter running smoothly and trapping the gunk. You can soak it and clean it to reuse one or two more times before tossing. I have 3 single tail goldfish in the tank so you know this sponge was put thru the mill!. I live in Arizona, it still worked even in my hard water

Nice idea for more thorough aquarium filtration

I really like the idea of how this is part of such a seemingly complete aquarium filtration system. I think fish will be healthier because of it. It's easy enough

I really like the idea of how this is part of such a seemingly complete aquarium filtration system. I think fish will be healthier because of it. It's easy enough to use with the appropriate filter housing.

Huge fan of fluval products. They do an exceptional job keeping the water crystal clear. They’re also very quiet. I clean the filter media once a month and my fish

The Fluval bio-foam filter works great, it’s easy to use and the Fluval brand usually comes in packs which makes changing the filter monthly very easy. My fish tank is much cleaner using this brand.

Love it

Was a little unsure about trying a new filter but so far I’m really loving it. It also seems like the filters will last a bit longer before needing to be change

Fits fluval filter system. Works as it should

This may be fine for a 20gal tank. I have a 55 and could not handle it. I have another king of filter in the same tank. The foam fits fine in the filter.

Quick delivery!

Needed maintenance on my aquarium and ordered items I needed without having to drive around to different pet stores, since not all have everything I needed.
