Air stone diffusers efficiently distribute oxygen in an aquarium. The NEO Air Stone Diffuser by Aquario features microscopically small holes resulting in very fine and thorough bubble diffusion to the entire aquarium. 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. This diffuser is clean in appearance and sports a low profile appearance to minimize in-tank equipment distractions. Similar to other diffusers, users are able to place it in the corner of a planted aquarium securely with the provided suction cup.

Why we like Aquario NEO diffusers:
Extremely fine bubble diffusion
Economical diffuser
Extended connector produces clean straight lines in the aquarium
Pre-bent for easy and quick installation
Smaller diffuser chamber reduces in-tank equipment visibility
Made from durable acrylic for shatterproof resistance

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.

With a further expansive line of water conditioners, fertilizers, and aquarium soils, Aquario equips hobbyists with premium planted tank supplies that support efficient, naturally beautiful aquascapes, making it a trusted go-to source for aquascapers who value both aesthetics and technical reliability.

Elegant bubbler

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)
