UP Aqua's Glass Diffuser is durable, and looks great! There are lots of diffusers out there, but nothing looks quite as nice as glass. Measures .75 x 1.25 x 2.5-inches. (1.9) x (3.175) x (6.35)-cm. Mini suction-cup included. Place in an area with good water movement, typically down low and connect to a CO2 supply.
