Twinstar CO2 Diffuser

Finest CO2 bubbles produced
Budget-friendly
Built-in bubble counter
Durable shatterproof acrylic construct
Works with all CO2 systems, even DIY setups


CO2 diffusers efficiently distribute CO2 in a planted aquarium. The Twinstar Diffuser features microscopically small holes resulting in very fine and thorough bubble diffusion. The microbubbles produced are able to diffuse into an entire aquarium, effectively allowing aquatic plants to absorb CO2 properly. Sleek and sturdy, the Twinstar CO2 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.
