Rated 4 out of 5 by Zabo56 The best at trapping scum!
I have been in the hobby for a long time and the quality of the filter cartridges have definitely gone down but they still work!

Rated 1 out of 5 by cicfancier1 Filter material has been degraded
I wondered why my aquarium water became murky after only 1 week after change. I tried doubling the filter bag and that did the job. Tetra has substituted thinner filtration material and therefore degraded the product to lower their cost. Customers don't expect replacement razor blades to be degraded. The Power Filter replacements are sold the same way. I will make my own filters out of batting material from now on. You've lost a customer.

Rated 2 out of 5 by Tomas It is well priced for a replacement filter
Filter bag could be of better quality and evenly cut on both sides. Meaning same lenght on each side going right or left. Put excellent price for Biobag filter!
