Tetra Whisper ATS26170 Assembled BioBag Filter Cartridges, Large 6 Count

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

they are good

It was not the same replacement filter that I needed. But I had opened one box so I can use the charcoal filter bags and charcoal with my assembly and that will work.

Love these bio bags....a main staple for any aquarium...other type media can be put in bag for there is enough room for addition. Just the best!

A few fell apart

Good Product

Love the product love the fast shipping price was fair

Easy to use

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

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.
