Chihiros External CO2 Diffuser 12/16

The Chihiros External CO2 Diffuser 12/16 is an inline CO₂ diffuser designed for aquariums using external canister filters. It connects directly to a 12/16mm filter hose, allowing CO₂ to enter the aquarium through the filter water flow instead of placing a diffuser inside the tank.

This external CO₂ diffuser helps keep the aquarium interior clean and equipment-free while supporting effective CO₂ distribution through the water flow. Its ceramic diffuser head creates fine CO₂ diffusion, while the aluminium and acrylic body gives a clean, durable finish.

The Chihiros External CO2 Diffuser 12/16 is the M size model and is suitable for small to medium aquarium setups using 12/16mm hose. It has a 30mm diameter, 113mm height, and requires around 0.15MPa / 1.5 bar minimum working pressure for proper operation. The diffuser head is replaceable, making maintenance easier for long-term CO₂ system use.
