This CO2 diffuser is used to create fine CO2 bubbles to provide aquarium plants with the carbon dioxide they need and ensure the nutrition and health of hydrophytes. The ceramic diffuser disc on this CO2 diffuser has atomic pores on its surface, which can produce fine bubbles when pressurized CO2 is passed through it. The fine bubbles created, rise slowly and ensure efficient diffusion of carbon dioxide in the aquarium. The CO2 diffuser is made of high quality aluminium material which does not rust, and it is strong and reliable to use. A suction cup mount is included to attach the diffuser on the tank.
