Flat Bottom CO2 Diffusers
Flat-bottom diffusers provide a stylish option for pollen-type CO2 diffusers. Available in a variety of sizes for aquariums ranging from nano-size through to 500L. 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.
