The Marina Complementary Air Stone is an ideal accessory to enhance the beauty of an aquarium and diffuse air into it, which at the same time creates some water circulation.
This complementary air stone can be connected to other air stones to produce prolonged and very spectacular bubble effects. It also increases the agitation of the surface water, speeds up the oxygenation process and helps the accumulated carbon dioxide to escape. Simply connect it to the air hose and place it in the desired location.
Size: 25 cm (10 in).
