AquaLabs Pro Inline CO2 Diffuser

Take your planted aquarium to the next level with the AquaLabs Pro Inline CO2 Diffuser, designed to deliver efficient carbon dioxide (CO2) dissolution and consistent distribution throughout freshwater planted aquariums. Developed with aquascapers in mind, this upgraded inline diffuser offers improved performance, reliability and a discreet installation for a cleaner, more professional aquarium setup.

Featuring an enlarged ceramic dissolution membrane, the AquaLabs Pro is designed to improve CO2 absorption and diffusion efficiency, helping deliver carbon dioxide directly into the water flow before it returns to the aquarium. Consistent CO2 availability is particularly important in planted aquariums, where carbon dioxide plays an essential role in photosynthesis and healthy aquatic plant development.

Unlike traditional in-tank diffusers, the inline design integrates directly into the outlet hose of an external canister filter, eliminating the need for additional equipment inside the aquarium. This keeps the aquascape free from visible diffuser equipment while allowing CO2 to be distributed through the filter's return flow.

The Pro model also features upgraded reinforced seals for improved leak resistance and long-term reliability. Combined with its durable construction and reduced cleaning requirements compared with conventional internal diffusers, it provides a practical solution for aquarists looking for a more streamlined CO2 injection system.

Whether you're maintaining a heavily planted aquascape or building a high-tech planted aquarium, the AquaLabs Pro Inline CO2 Diffuser is an excellent addition to a well-balanced CO2 system.

Available in two sizes to suit different external canister filter hose diameters: 12/16mm and 16/22mm.
