Rated 1 out of 5 by from They stopped making the small size I have 2 fish tanks and each tank has 2 filters in them. I went to purchase new filters and found out the small size was discontinued. the last time I purchased them I got 2 boxes of 6 count ones. I am so disappointed and now have no idea what to use to replace the small without buying 4 new filters.

Rated 1 out of 5 by from No instructions I bought the 3-gallon tetra tank from Amazon and it comes with basically no instructions. Doesn't say which direction to put in filter, doesn't say how long. I have to come to internet. Terrible, unlike most people I still read and instructions would make sense. Also sad is that a large full side picture on box does not even show filter in the tank. I will not recommend, We only bought on amazon because my son came home with a fish in a small container and I needed something fast.

Rated 1 out of 5 by from New filters are terrible I've been keeping fish for 30 years and have always used these, but they're so thin now, I can't stand them! I have to fully change the filters every 3-4 weeks, it's terrible.

Rated 4 out of 5 by from 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 from 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 from 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 from 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.
