UBeesize Aquarium Filter Media Floss, 6 ft Cut to Fit Pond Filters for Outdoor Ponds and Fish Tank, High Efficiency Aquarium Filter Material, No Dye and Reusable Filter Floss

Easy to cut to size to fit our external filters. It’s nice to not have to keep multiple sizes of replacement filters and instead just be able to take what I need from here. Filtered the water well.

I cut the filter to fit the aquarium, works great and more affordable than buying it! Helps keep the water clear and easy to switch out.

This filter floss works well for what it is meant to do. It’s affordable, easy to use, and does the job without much fuss. A solid choice for maintaining cleaner tanks. Worth trying if you’re looking for simple filtration.

Cleans fine but disintegrates when you clean it so it’s good for one time use only.

Cheap, thin, single layered. Only plus is easy to cut

This works perfectly for me. I can now replace the filter in my cat’s fountain anytime. She loves it, and her water will be perfectly fresh all the time.

I bought this since it was difficult to find the right size filter for my fish tank. It came in a large sheet and I just cut off a strip and folded it up to use as a tank filter. Works great.

I liked it because it comes with enough filter to use as much as you want. For the price it's fine. In other specialty stores it's more expensive.
