Whisper air pumps provide reliable service at an economical cost. Efficient and easy-to-use, Whisper air pumps can handle the aeration needs of aquariums from 10 to 100 gallons.

Tetra Whisper Air Pumps Help Keep Your Tank Quiet

Tetra Whisper Air Pumps keep your aquarium oxygen levels high, helping keep your fish healthy. And with seven different sized pumps, there is sure to be one that is perfect for your aquarium. This line of air pumps has a unique dome shape and rubber feet. This flattens sound wave frequencies and helps prevent them from reflecting off of surfaces such as tables and shelves, allowing your pump to produce minimal noise. Whisper Air Pumps can be used in deep tanks (up to 8 feet deep), and have enough strength to power long decorator air stones, multiple air stones in one or more tanks, and protein skimmers for salt water aquariums. Every Tetra pump also comes with a lifetime limited warranty.
