Green Leaf Aquariums has introduced a new line of Atomic Co2 Diffusers that will take co2 distribution to the next level with ease for any planted tank enthusiasts. These diffusers are so efficient at what they do that you will be able to save time and money on co2 refills.
Where we use to use 3-4 or 5-6 bubbles per second, we can now relax and slow things down and work easily with 1-2 bubbles per second. These diffusers require a working pressure of 30psi along side with the use of our co2 resistant tubing that is better suited at higher working pressure.
The video plays well in a few of the HD settings.

This diffuser does not require one to function, however using one will not effect its performance either.
