People have a misconception about filters. Most including myself think if they get a great big filter in a small tank it will be completely clean. Wrong! Filters filter the water in the tank they do little for poop and leftover food that settles to the bottom. I had am fx5 in a 40 gallon tank and still had to do weekly water changes. I also had to use a syphon to clean the debris weekly. With that being said, your filter is probably doing its job just fine. As long as it isn't all clogged up.
