CO2 diffusers efficiently distribute CO2 in a planted aquarium. This extended long NEO diffuser from Aquario features microscopically small holes resulting in very fine and thorough bubble diffusion along with an extended connection piece. The longer extended connection piece allows the user to keep clean lines within the aquarium and minimizes the need for suction cups that would usually be used to keep CO2 tubing straight in-tank. In addition, the extended length is already pre-bent in a perfect u-shape to hang on rimless aquarium tanks seamlessly to match a cleaner aesthetic.

With design features improved, the extended NEO CO2 diffuser still provides the same microbubbles that are perfect in size and easily diffused into an entire aquarium, effectively allowing aquatic plants to absorb CO2 properly. Sleek and sturdy, the Neo Diffuser is made from high-quality, 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. 

Why we like the Aquario NEO diffusers:
Finest CO2 bubbles produced
Extra long connector provides sleek and clean appearance
Pre-bent for easy and quick installation
Smaller diffuser chamber decreases in-tank equipment distractions
Durable shatterproof acrylic construct
Works with all CO2 systems, even DIY setups

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.
