Finest bubbles produced
Budget-friendly
Smaller diffuser chamber decreases in-tank equipment distractions
Durable shatterproof acrylic construction

Air stone diffusers efficiently distribute oxygen in an aquarium. The NEO Air Stone Diffuser from Aquario features microscopically small holes resulting in very fine and thorough bubble diffusion. The microbubbles produced from its large surface area effectively increases the amount of dissolved oxygen in an aquarium tank. Sleek and sturdy, the Neo Air Stone Diffuser is made from transparent acrylic and is not easily broken when performing aquarium maintenance. Similar to other diffusers, users are able to place it in the corner of a planted aquarium securely with the provided suction cup.
TIP: Soak the diffuser in water for 30 minutes before use to produce smaller bubbles.

TIP: When bubble diffusion is slowed, soak it in bleach for 10 minutes and rinse with water thoroughly to ensure any residual bleach is gone.

Great Diffuser

"Great diffuser/airstone and looks nice paired with the Aquario CO2 diffuser"

— jesse p. (5/5)

Elegant bubbler

"Bubbles well, the sound was a little bit more than I expected. This can be remedied with regulator valve."

Great Diffuser

"Outputs the smallest bubbles of any diffuser I've ever owned."

— David C. (5/5)

Great airstone

"This is a great airstone. Looks good too. I got the largest on and fits perfect and all the way to the bottom of my UNS 40C. Packaging threw me off because it said CO2 diffuser, but this is an airstone. Fine bubbles."

— Alexander M. (5/5)

Beautiful

"Great product. Didn’t want a tan/brown colored diffuser and this white one is pristine and a sexy I might add haha. No extra u-bend tube making it super sleek. Tube is ‘bendable’ to a limit but the curb hugs the glass rim perfectly to make it stay put so no suction cups would be needed. Definitely recommend."

— Jayson B. (5/5)

Co2 diffuser

"I liked the idea of this diffuser but then i felt like i had multiple birds in ma tank with all the chirping. Also i realized it would sometimes let go of a big bubble"

— Marvzky (3/5)

Q&A

Does this come with a U-pipe connector that fits over the top of the rim? Or does it just connect to a hose? Alternatively, is it bendable?: Mine came with a u-bend piece. Also, you would need a heat gun or something to bend it because it’s pretty rigid normally. It flexes, but it goes right back when you let go. I think it’s made of acrylic.
