The Marina complementary air stone is an ideal accessory to enhance the beauty of an aquarium and to diffuse air, creating some water circulation at the same time.
This complementary air stone can be connected to other air stones to produce prolonged and very spectacular bubble effects. It also increases water agitation on the surface, accelerates the oxygenation process, and allows accumulated carbon dioxide to escape better.
Simply attach it to the air hose and place it in the desired location.
Rectangular shape.
Dimensions: 14 cm (5.5 in).
