Penn-Plax Rice Mill Aquarium Ornament

Add a touch of charm to your aquarium with this Penn-Plax Rice Mill Aquarium Ornament! Not only will it look beautiful in your tank, but it will also help aerate it. The wheel spins from the bubbles that come out from the mill, providing your finned friends with much needed air. To use, simply connect the ornament to a standard 3/16 airline from your air pump (sold separately), sit back and watch the steady stream of bubbles flow. To adjust the motion and volume of the air, use your pressure control valve (sold separately). This ornament is crafted from a durable plastic resin that is safe for your freshwater or saltwater/marine aquarium. This entertaining Action Air ornament is plenty of fun to watch, and you’ll be creating a healthier environment for your fishy friends, too.
