Whisper 20i Gallon Internal Power Filter

Your fish are only as healthy as their water is clean. Many factors have an impact on the health of your aquarium water, such as uneaten food, fish waste, and decaying plant parts. You want to ensure the water is as clean as possible not only for your fish's health, but to keep your aquarium looking great. You also don't want to be constantly changing out cloudy water for clean water. Tetra Whisper 20i Gallon Internal Power Filter uses three-stage filtration to quietly and conveniently keep your aquarium looking and performing its best. The dual-sided mesh of the Bio-Bag captures fish waste and debris and the activated carbon absorbs discolouration and odours. Biological filtration is provided by the Bio-Scrubber, and the entire filter is submersible. Features: Three-stage filtration Captures waste and debris Absorbs discolouration and odours Biological filtration Water flows over bacteria-rich bristles Easy to change cartridges Quiet and convenient operation Ideal for up to 20 gallon aquariums
