40i Super Quiet Whisper In Tank Aquarium or Terrarium Filter by Tetra is ideal for 20 to 40 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 inches of water, making it ideal for low water level environments like amphibian aquariums, terrariums, turtle tanks or waterfalls. Complete 3-stage biological, chemical and mechanical water filtration is provided from the same Whisper Bio Bag Filter Cartridges used in the famous Whisper Power Filter. Whisper Bio Bag Filter Cartridges contain precisely the amount of activated carbon and filter mesh area to provide superior aquarium filtration. UL listed. Filters can be adjusted easily on the water height using the included suction cups and bracket. Whisper In-Tank 40i takes a large bio-bag, for aquariums 20 to 40 gallons, and filters 170 GPH of water. Please consider the next size larger if your tank has a large amount of fish or live plants.
