What are the Tetra filters?
These are primarily made for smaller aquariums (under 20 gallons) and are placed inside the aquarium to provide water movement.
Typically use disposable cartridges and hang on the back edge of your aquarium. Often known as Hang on Back filters or HOB filters.
Whisper IQ Power Filter
Whisper IQ filters use StayClean technology for easier maintenance and healthy fish. A sound barrier decouples motor from filter to give you the quiet you’ve always wanted. With better materials and impeller upgrades, these filters are made to last. It’s time for a filter that’s easy to use and easy to clean!
Whisper IQ technology gives you a filter that is does the job while staying quiet. The SoundShield provides a barrier between the motor and filter to minimize noise. Combine that with vibration dampening technology and these filters give you quiet power to keep your tank clean.
