I have used Aquaclear filters for years and have always been extremely satisfied with the ease of using their products.They're ready to go,long lasting,and certain parts like the sponges,bio balls,et.,can be used for a very long time.

Pros: Easy to find ready to use very convenient

Cons: none

To keep water quality healthy, you must change this every month. If you do so, the water stays clear and healthy! And it's easy to do and you don't have to get your hands all in the tank.
