Cascade presents the Nano Air Pump. This air pump quietly aerates and oxygenates fish tanks at a rate of 1.2 Liters per Minute (1.2L/Min), and is the perfect size for small desktop aquariums or Betta bowls. It connects to an electrical wall outlet via a 26.5” long power cable, and is safe for both freshwater and saltwater fish tanks.

In addition to holding things in place, the vibration absorbing base ensures no unnecessary noise is heard. Please Note: airline tubing and accessories sold separately. Please Read Directions: For optimal performance and longevity, please read and follow included directions. Always have a drip loop or safety check valve, and never place into water.
