CO2 that bubbles straight into the tank without being broken into fine bubbles mostly escapes to the surface before plants ever get to use it. The Dymax CO2 Plastic Atomizer breaks incoming gas into a fine mist, giving CO2 far more contact time with the water before it can rise and escape.
Why Atomization Matters for Planted Tanks
A CO2 diffuser or atomizer's whole job is dissolving as much of the injected gas as possible into the water column, since undissolved CO2 that reaches the surface is simply wasted — both the gas itself and the money spent on the cylinder refill.
What the Plastic Atomizer Offers
- Breaks CO2 into fine bubbles for significantly more surface area and dissolution time than a plain airline outlet.
- Budget-friendly entry point into atomized CO2 diffusion compared to glass or ceramic options.
- Simple inline installation on standard CO2 tubing.
How to Use It
- Position it low in the tank and ideally under flow from a filter outlet or powerhead to spread the fine bubbles further before they rise.
- Pair with a bubble counter upstream to dial in and monitor your injection rate.
- Clean periodically, since the fine diffusion surface can clog with algae or mineral buildup over time.
