Air Stone - Air Disc 4" *Special Order**

Air diffusers are great for aerating or circulating nutrients in your tanks or reservoirs.

These air diffusers incorporate suction cup feet to keep your Ecoplus Air Disc secured without fear of it moving around or flipping.

The air diffusers have a built-in 3/8 in 90-degree elbow fitting that ensures the airline connects freely to your fitting and prevents the airline from kinking at the base of the fitting.
