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!

Rated 5 out of 5 by ShaShaGrace I love that I can leave the carbon out!
I don't like to use carbon in my filters unless I'm removing medication from the tank, and this unassembled filter give me that option! I recently purchased a Whisper EX that only has pre-assembled cartridges with carbon, and I am very unhappy with it for that reason alone. This is a great choice if you want options for your filtration, but it's still super easy to use if you don't. It is also relatively affordable.
