The Chihiros External CO2 Diffuser is an inline CO2 solution that connects directly to your canister filter hose. By placing the diffuser outside the aquarium, you keep the scape clean and free from visible hardware.
CO2 is mixed into the filter flow and carried evenly throughout the tank, providing a stable supply even in larger or densely planted aquariums. This makes it an excellent choice for aquascapes where you want minimal equipment inside the tank.
