Welcome the real star of the CO2Art diffusers collection- the NEW In-line CO2 Diffuser with a replaceable ceramic membrane!

The V2 version of our classic In-line CO2 Diffuser comes with an improved ceramic membrane made with Fine Mist Technology providing you with the highest dissolution rates!                                                        

The CO2Art In-line Diffuser optimises the injection for the best CO2 absorption and less waste. CO2 bubbles pass through the porous ceramic membrane and are diffused into streams of tiny bubbles. The increased saturation of the CO2 in the water column is highly beneficial for healthy and fast plant growth.

If you run an external filter, the In-line diffusion method is perfect. Thanks to being able to position the device outside the aquarium, there is more space for plants inside without additional equipment spoiling the view. The metal body of the diffuser makes the device crack-resistant and durable. The membrane included with the diffuser is replaceable with our replacement Ceramic Membrane (sold separately)                                                  

Depending on the hose dimension, you can choose from two sizes.
