CO2 Inline Diffuser

Add CO2 through your aquarium's external filter plumbing with the Week Aqua CO2 Inline Diffuser. This external atomizer places the diffusion chamber in the hose line, helping keep the display focused on the aquascape. Its replaceable diffusion element and clear chamber make the working parts easy to see.

Choose the diffuser by your filter hose's inner and outer diameters:

• Diffuser 08/08: CO2-0808, for 8/12mm hose.
• Diffuser 12/12: CO2-1212, for 12/16mm hose.
• Diffuser 16/16: CO2-1616, for 16/22mm hose.
• Diffuser 20/20: CO2-2020, for 20/26mm hose.

Each size has a CO2 gas connection for 4mm inner / 6mm outer diameter tubing. The catalogue specifies a working pressure above 22psi.

Pair the diffuser with Week Aqua CO2 Tubing. For convenient access to compatible filter hose connections during maintenance, explore Quick Disconnects. Use a CO2 Drop Checker Kit as a visual reference when adjusting your CO2 setup.
