For 50 years, fishkeeping enthusiasts have looked to the Tetra name for products and solutions that add ease and beauty to their home. Whether you're an experienced hobbyist or just starting out, Tetra has everything you need–-from a large variety of quality fish food and innovative equipment to test kits and decor. The Tetra® Whisper® Internal Power filter is made for aquariums up to 4 gallons. Small cartridges are easy to change, always keeping your aquarium water clean. Both mechanical and chemical filtration work to provide you with a clean and clear tank. Water flows through cartridge floss, trapping debris and waste , while the Ultra-activated® carbon removes odor and discoloration. The 27 GPH motor cycles a 4 gallon aquarium more than 6 times per hour. The space saving design is easily hidden by decor in your tank, with an adjustable clip that accomodates high and low water levels.
