Nano CO2 Diffusers

Nano diffusers were the among the first CO2 diffusers to be created, and their simple but effective design has stood the test of time and still a popular option for those making their first entry into the aquarium CO2 arena. CO2 is forced through a white ceramic disc, which produces a mist of small CO2 bubbles. These small bubbles are more readily diffused into the aquarium water than a single large bubble, and therefore greater levels of diffusion are achieved.
