Tetra Whisper Aquarium Air Pumps (formerly Tetratec Deep Water Air Pumps) are Tetra's most powerful line of air pumps. The Whisper is excellent for delivering air to protein skimmers, tall tanks, even ponds, and makes an ideal deep water air pump!
The pumps are designed for situations that produce more back-pressure, such as deep tanks (up to 8 feet deep), long decorator air stones, multiple air stones in one or more tanks, and protein skimmers for salt water.
