I love the Finnex aquarium filters at Amazon, but they don't have their own replacement filters. I found these NICREW Replacement Filter Cartridges fit perfectly! The price is very reasonable, but if you want to extend the use of the cartridge, you can rinse it once or twice and reuse. (This depends on how often you do a water change, and how much poop your particular fish produce. lol)

We use this filter for our betta tank. They work great And they're easier to find than the original water filter we purchased at Petco.

These filter cartridges looked fine. However I was attempting to find a cartridge that would work in an unusual aquarium filter. These were not compatible
