Penn Plax Action Air Decorations bring animation, charm, and life to your underwater world while aerating your tank. The action of this treasure chest opening and closing reveals the interior treasure while bubbles escape the chest to provide your tank with much needed air. Simply connect the ornament to a standard 3/16 airline from your air pump (not included) and watch as the steady stream of bubbles opens and closes the treasure chest. Use your pressure control valve (not included) to adjust the motion and volume of air, if desired. Each Action Air ornament is made from a durable plastic resin that is safe for your freshwater or saltwater / marine aquarium. Fun to watch and entertaining for all, Action Air ornaments fit in almost any tank and come in a variety of styles and sizes so you can continue to add to and customize your aquarium design.
The Treasure Chest measures approximately 2.25"L x 1.75"W x 2.75"H when open.
