Tetra Whisper ATS26170 Assembled BioBag Filter Cartridges, Large 6 Count

Packaged item fit as described and filters great.

I was concerned that this would not fit my filter as the package design was different from what I was used to. However it did fit perfectly and I am very happy. Did not have to go to the big box store and it was delivered right to my door.

Great product and fast shipping

Arrived on time and fit filter perfectly.

I am very dissatisfied with the quality. A good dusting of Charcoal fragments were inside the box. I shook the filters over a white paper towel and they never stopped leaking charcoal bits. I tried one in the pump anyway and a slurry of charcoal coated the top of the water. I had to skim off the floating charcoal. The original filter that came with the pump was much better quality and these are trash when comparing them side-by-side.

As described

Had to change filter bag within a week. Other brand I could change once a month.

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

Easy to use..for my 55 gallon fisj aquarium.

Great service & Product
