Tetra Whisper Aquarium Power Filters



Tetra has long been known for its Whisper hang on filtration system. When the product was first introduced more than 20 years ago, it was considered reliable and easy to use, and quickly over took the marketplace as the preferred filter. Technological advances and changes in demographics and the reasons for adopting or abandoning the hobby of keeping fish suggested that Tetra conduct an extreme filter makeover, one with a goal of addressing the main concern of aquarium owners: to make keeping fish more enjoyable by making it easier, cleaner and more intuitive.
