Co2 Atomizer- Carbon in the form of carbon dioxide (CO₂) is one of the most important nutrients for a healthy growth of aquatic plants. Ideally the aquarium gets supplied with carbon dioxide via a CO₂ system. The diffuser or atomizer plays a big part in this. Diffusers with a membrane are particularly efficient for this purpose, since they atomize the CO₂, i. e. they turn the gas into many tiny bubbles, which facilitates the dissolution of the gas in the aquarium water. For atomization, pressurized CO₂ is forced through a finely pored ceramic membrane. Many different membrane diffuser types and designs are available.
