Bring professional-grade gas diffusion to your planted aquarium without sacrificing the clean lines of your scape. The Chihiros External CO₂ Diffuser mounts inline on your canister filter’s return hose, hiding the hardware in your cabinet while delivering a micro-mist of CO₂ directly into the out-flow. Key Features Crystal-clear view, zero clutter – No more glass diffusers or bubble counters inside the tank; all you see is plants. Engineered for efficiency – A precision-fired ceramic membrane atomises CO₂ into ultra-fine bubbles. The longer dwell time in the hose means more gas dissolves before reaching the display, reducing wastage. Built to last – The anodised aluminium shell shrugs off high pressure and humidity, while the acrylic window lets you monitor bubble density at a glance. Service-friendly – Twist off the front cap, swap the ceramic disk, and you’re back in action in minutes. Fits your setup – Choose the size that matches your filter hose and flow rate. All models accept standard 4/6 mm CO₂ tubing via the included compression fitting.
