Marina air stones are ideal as an accessory to both enhance the beauty of an aquarium and to diffuse air, thereby creating some water circulation.
In addition, Marina air stones increase water agitation at the surface, accelerate the oxygenation process and allow accumulated carbon dioxide to escape more effectively. Simply connect them to the air hose and place them in the desired location.
