Aquario Neo Inline CO2 Diffuser 16/22mm

The Aquario Neo Inline CO2 Diffuser 16/22mm integrates seamlessly into the filter outflow line between the canister filter and the return fitting, completely eliminating in-tank CO2 hardware for the cleanest possible aquascape presentation. CO2 is injected into the flowing water stream inside the diffuser body, where the fine ceramic element breaks it into micro-bubbles that dissolve almost entirely before reaching the aquarium, resulting in highly efficient CO2 utilisation with minimal surface disturbance. The 16/22mm hose barbs are compatible with the outflow tubing of popular canister filters including Eheim, JBL, Fluval, and Oase models. The clear acrylic body allows visual inspection of bubble dissolution, and the unit disassembles for straightforward ceramic disc maintenance. Ideal for medium to large planted tanks where aesthetic cleanliness is a priority.
