Review on Tetra ReptoFilter Cartridges Whisper Technology by Dana King

We have been using this filter since Christmas when we gave our son his turtles. They were so stinky! He was obsessed with turtles for a while and that was the only thing he wanted for Christmas. By coincidence, one of our neighbors was looking for a new home. The filter they had didn't work well and his whole room and hallway smelled like turtle even after a water change. We bought this filter and after a few hours the smell was gone. The replacement cartridges are very easy to replace. I'm still amazed that I changed this filter. I highly recommend it.
