Tetra® Whisper Bio Bag Cartridges
Not bad for the price
I wouldn't call this the best filter on the market, but considering the price investment, it does a pretty good job. For a small tank, there aren't many options that don't create a turbulent environment for fish. This one has a nice, gentle flow. My betta is quite pleased with it. Filters are easy to change and inexpensive too.

Good for its size!
Perfect for a small tank. I use it in one of my betta hospital tanks and its perfect for it. First day I set it up and the water was already clear. Doesn't make any loud noises, very small, and it doesn't rip or hurt my bettas fins. It was also very easy to set up. Had some difficulty with the air line because it was a bit small but I got it to fit.

Overall great filter for small tanks
I purchased this filter about a month ago and the water in my 2.5 gallon betta tank has been crystal clear ever since. It filters extremely well, and does not make too much of a current for my betta fish. He seems to enjoy the movement in the water more than the stillness. The only flaw in this filter is that it is not quiet. It is relatively loud, but I can still fall asleep with it in my room at night. I wish it was slightly quieter, but for the price it does an amazing job. Overall, it is the best filter for small tanks that I could find, and I would highly recommend it (unless you are too light a sleeper).

Great filter for small tanks
I used this for my 2.5 gallon live plant tank. It has worked great. It keeps the water clean, doesn't take up much space, and has a very mild flow. The only problem is that the air pump it comes with makes a buzzing noise when it touches something else. The sound it makes is soothing, and it hasn't even sucked up one of my baby guppies.
