The super quiet Whisper in tank aquarium or terrarium filter that is ideal for 2-10 gallon tanks. The Whisper in tank filter is easy to conceal inside your aquarium; hide it behind a plant or other decorative object and from the front it is practically invisible. Space-saving design can be flush with the wall and operates in as little as 2 in. of water, making it ideal for low water level environments like amphibian aquariums, terrariums or turtle tanks. Complete 3-stage biological, chemical and mechanical water filtration is provided from the same Whisper Filter Cartridges used in the famous Whisper Power Filter. Whisper Filter Cartridges contain precisely the amount of activated carbon and filter mesh area to provide superior aquarium filtration. UL listed.

My 10 gal. tank is filled 1/3 way up with water for a turtle. I couldn't be happier!! The filter is held on by suction cups, so you can put it lower in the tank with no problem! I have been using this brand for 1 year [ this is my second one ONLY because my husband didn't realize you have to save the bio-scrubber and replace the bags]. If I replace the bags every other month, the tank stays crystal clear.

This is a great little filter. I have it in my 10 gallon tank and it cleans up all the mess they make. The cartridges are cheap and don't need to be changed often. I would recommend it to an beginning hobbyist definitely. No cons so far.
