CO2 Inline Diffuser 16/22mm

Inline CO2 diffusers represent one of the most efficient and visually clean methods of CO2 injection in planted aquariums. This 16/22mm model installs directly onto the outlet tubing of a canister filter, where CO2 is injected into the fast-moving water flow returning to the tank. The turbulence generated by the filter pump dissolves the CO2 almost completely before it re-enters the aquarium, significantly increasing dissolution efficiency over in-tank diffusers. With no visible equipment mounted on the aquarium glass, the result is an uncluttered aquascape. This unit suits 16mm inner diameter and 22mm outer diameter canister filter tubing, common on most mid-range to large canister filters.
