Pumping air into your aquarium, for which you’ll need aquarium airline tubing and aquarium tubing connectors, is recommended because many fish prefer certain levels of dissolved oxygen in their water. You can improve water circulation, by hooking up your aquarium air pump tubing to some type of air dispersion device such as an air curtain or air stone. We offer all of the necessary equipment for keeping your fish tank maintained properly, such as aquarium airline tubing, airline check valves, airway control valves, metal air dividers and a wide variety of aquarium tubing connectors.
