The Chihiros In-Line/External Diffuser (16/22mm) connects externally to your canister filter’s return hose to dissolve carbon dioxide directly into the water flow. It uses a micro-pore ceramic disc to create ultra-fine bubbles. This keeps equipment out of your display tank for a clean aquascape. It requires a minimum working pressure of 1.5 bar (0.15 MPa).

Key Features and Specifications:
- Hose Compatibility: Fits standard 16/22mm aquarium filter tubing.
- Material: Built using durable aluminium and acrylic body components with a ceramic atomizing disc.
- Aesthetics: Removes clutter from inside the tank glass by shifting CO2 injection to the external return line.
- Maintenance: Features a replaceable internal ceramic membrane insert for extended product life.
Installation and Usage Tips:
- Placement: Install on the return/pressure side hose (water flowing from the filter back into the aquarium).
- Pressure Requirement: Ensure your CO2 regulator can supply a minimum working pressure of 1.5 bar (150 psi / 0.15 MPa), as micro-pore ceramic discs need higher initial force than standard in-tank diffusers.
- Security: Tighten hose connections properly to prevent leaks under filter pressure.
