The Marina complementary air stone is an ideal accessory for enhancing the beauty of an aquarium and for diffusing air, creating some water circulation at the same time.
This complementary air stone can be connected to other stones to produce spectacular, extended bubble effects. It also increases water agitation on the surface, accelerates the oxygenation process and allows accumulated carbon dioxide to escape more effectively.
Simply attach it to the air hose and place it in the desired location.
Rectangular shape.
Dimensions: 25 cm (10 in).
