CO2Art In-line Diffuser - Optimize CO2 Injection for Aquarium Plants

The CO2Art In-line Diffuser optimizes CO2 injection for better absorption and minimal waste. As CO2 bubbles pass through the porous ceramic membrane, they are diffused into streams of tiny bubbles. This increased saturation of CO2 in the water column promotes healthy and rapid plant growth.

Key Features:

  • Optimized CO2 Injection: Enhances CO2 absorption and minimizes waste.
  • Porous Ceramic Membrane: Diffuses CO2 into fine bubbles for better dissolution.
  • Space-Saving Design: Ideal for use with external filters, allowing more space inside the aquarium for plants and maintaining a clean aesthetic.
  • Durable Metal Body: Crack-resistant and durable, ensuring long-lasting performance.


Available Sizes

  • 12/16 ID/OD: Inside Diameter / Outside Diameter ~ 13mm (tubing diameter)
  • 16/22 ID/OD: Inside Diameter / Outside Diameter ~ 17mm (tubing diameter)


Operating Requirements:

  • Requires a minimum of 30 psi working pressure.
  • Must be used with CO2 pressure-rated tubing only.
  • Do not use with silicone tubing.
  • Tubing must be acid-resistant and rated for high working pressure.

The CO2Art In-line Diffuser is perfect for those running external filters, as it can be positioned outside the aquarium, leaving more space for plants inside without additional equipment spoiling the view. Order now to enhance your aquarium’s CO2 injection system!
