Hagen Marina Elit 1-Inch Cylinder Diffusion Aquarium Air Stone - 2 Pack

Marina Cylindrical Airstones (1" – 2-pack) – A twin pack of small 1-inch cylindrical airstones for adding bubbles to your aquarium. Each airstone connects to an air pump via airline tubing and creates a stream of fine bubbles that improve water oxygen levels and circulation. The small size is perfect for placing in tight spots, small tanks, or even inside corner filters or ornaments. You get two in this pack, so you can either use them in different tanks or distribute them in one aquarium for even aeration. They’re washable and reusable, providing an easy and economical way to enhance your aquarium’s aeration and visual appeal.
