Great replacements for 10 gallon tank. Catch all the gunk in the tank. Easy to change.

  • They do the job
Size: Large, 9-Pack
I bought these filter cartridges hoping for a cost-effective option for my Tetra Whisper filter. They fit well and seem to do an okay job of filtering out debris. However, I've noticed they don't last quite as long as the original Tetra brand cartridges. After a few weeks, the water flow starts to decrease, indicating it's time for a replacement. They're reasonably priced, which is a plus, but if you're looking for top-notch filtration efficiency and longevity, you might want to stick with the Tetra branded cartridges. ... show more

  • Caused Cloudiness
Size: Medium, 9-pack
Poor product. Fish tank with only one goldfish clouded up within two days of use. My poor goldfish lost its energy and settled down to the bottom of the tank. Switched to the brand name filter and the fish revived. Very disappointed.
