$37.99

High Quality Stainless Steel in-Tank CO2 IO Diffuser

Only the best by Co2Art

An IO Diffuser optimizes the CO2 entering the aquarium for efficient plant absorption and less waste. As CO2 bubbles pass through the porous diffuser, they are diffused into streams of tiny bubbles. With increased surface area, the tiny CO2 bubbles are readily dissolved into the water, increasing the saturation of CO2 in the aquarium ecosystem.

The stylish high-quality stainless steel body will give your setup not only the highest dissolution rate but also a touch of luxury. Excellent CO2 dissolution rates thanks to new nano co2 mist technology membrane, easy maintenance and durable materials make IO Diffuser a perfect choice for novice and expert aquascapers alike. Designed to be used as a regular glass CO2 atomizer diffuser, but offering higher CO2 dissolution rates.

Choose from two different sizes;

  • Small for aquariums below 40 gallons
  • Large for aquariums above 40 gallons

Note: Please allow the diffuser to soak in the aquarium water for at least 2h before pressurizing the diffuser. In the beginning, the diffuser will produce large bubbles around the ring. Over the first 24h of use, all the ceramic pores will fill with water and bubble size will decrease to the optimal size.


CO² systems are essential for successful aquascaping. This enables aquatic plants to have greater access to Carbon dioxide, which allows a greater selection of aquatic plants to grow well in the tank. So, whats in a CO2 System: CO2 cylinder, CO2 Regulator with attached solenoid and bubble counter, CO2 high pressure tubing, CO2 diffuser, and check valves.
