The Aquario NEO CO2 Diffusor U Type is an acrylic CO2 Diffusor. The special ceramic membrane produces a fine mist and the CO2 gets dissolved very quickly. Perfect for planted tanks.
If the lower part is completely filled with water, the bubbles can also be counted directly in the diffuser without any problems.
Before use, immerse the diffuser in water for 10 minutes so that all the air in the diffuser is displaced. If there is still air in the diffuser, larger bubbles may form at the bottom of the diffuser ceramic.
