Tetra Whisper In-Tank Filter 40i for 20-40 Gallon Aquariums

The Tetra Whisper 40i Internal Filter is an exceptional solution for aquariums, delivering supremely quiet and efficient 3-stage filtration. Designed to be submerged, this filter conveniently mounts on the interior of your tank rather than protruding from the outside. This unique feature allows aquarists to position their aquarium flush against a wall, easily concealing it with decorative elements.

Included with the filter is an air pump that generates bubbles, which effectively circulates water through the filtration system. This process not only filters but also oxygenates the aquarium, ensuring a healthy environment for its inhabitants. Water first passes through Ultra-Activated carbon, which performs the important task of absorbing unpleasant odors and reducing discoloration, thus maintaining water clarity. Following this, the water flows through the dual-sided mesh of the Bio-Bag Filter, adeptly trapping debris and fish waste, ensuring that the tank remains clean and the fish thrive.

The Tetra Whisper 40i is designed to filter water at a remarkable rate of up to 170 gallons per hour while simultaneously oxygenating it. The filter comes equipped with a handy mounting clip that allows users to adjust it effortlessly to accommodate varying water levels, making it suitable for diverse aquarium setups. Each unit includes not just the filter but also the air pump, 2 feet of airline tubing, and one large Tetra Whisper Bio-Bag Filter cartridge. It is recommended that the filter cartridge be changed monthly, and smaller replacement cartridges are available for purchase.

This filter is ideal for aquariums ranging from 20 to 40 gallons. Since its inception in 1951, Tetra has established a comprehensive expertise in fish care, and hobbyists have consistently turned to this trusted brand for products that enhance both the ease of maintenance and the aesthetic appeal of their aquariums. Regardless of whether you are a seasoned aquarist or just beginning your fishkeeping journey, Tetra offers a wide array of options.
