Review on 🐠 Aquarium Filtration with Tetra Whisper Bio-Bag Filter Cartridges by Nancy Ruesink

I bought these for use in my small aquarium that only has 1 fancy goldfish. I'm not happy with how quickly they clog. The water in my aquarium stays clean, but this filter became clogged with dirt within 5 days - so much so that the filter started sounding like Darth Vader's breath. I had to change it. The second lasted only a day or two longer. I guess you could look at it as doing its job, but I've had a different variety before and it didn't clog up as quickly. The water in the aquarium looks the same (clean) in both cases. Since they have a plastic backing, I'm not thrilled with how quickly I have to dispose of them. I will choose another type when they run out.
