It is simple to use and the current flow allows air to circulate in the water. There is nothing special except it came with my tank. Pros: The filter does a good job at cleaning my 10 gallon aquarium and I have over 30 fish including my fry. The filter pads are inexpensive Cons: Noise might be too high. Lasted me for about 4 years. (It might be user error since the motor runs but it is not sucking up water).
