Tetra Whisper ATS26170 Assembled BioBag Filter Cartridges, Large 6 Count

Comes assembled and easily fits into the filter with no issues. Keeps the tank pristine.

Great product and price as well.

love the ease of use and is very quiet

Easy to use

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 filters work as expected.

Works great

Will keep the aquarium clear and the fish happy. . .and alive.

Perfect!

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