Tetra Whisper ATS26170 Assembled BioBag Filter Cartridges, Large 6 Count

These are great. keep the 10-20 gallon turtle tanks clean. I have a small mud turtle and a baby musk turtle.

I like the fact that these are assembled and ready to use,perfect!

These are my favorite filters. They are less expensive on Amazon than at the pet store.

Thanks received in no time.

Ive only ever used these filters. They fit the filtering system I use and help clean the tank water. Whenever the water gets cloudy I just change the filter and within an hour the water is crystal clear again.

The item was wrong size

As described

Perfect!

Love the product love the fast shipping price was fair

Been using these for years now. They work just fine. My turtle loves his tank.
