Inline Diffuser - 12/16

The CO2 Art Inline CO2 Diffuser is the ultimate solution for efficient CO2 injection in aquariums with external filters. Designed for use outside the aquarium, this diffuser keeps your tank clutter-free, allowing more room for plants while delivering superior CO2 absorption.

The V2 version of this classic diffuser features an upgraded replaceable ceramic membrane made with Fine Mist Technology, which optimizes CO2 dissolution rates. The diffuser transforms CO2 into streams of tiny bubbles, maximizing the saturation of CO2 in the water, leading to healthier, faster-growing plants.

The CO2 Art Inline Diffuser is available in two sizes to fit your filter setup:

12/16mm (ID/OD ~13mm) for smaller filters.

16/22mm (ID/OD ~17mm) for larger filters.

The diffuser’s durable metal body is crack-resistant, ensuring long-lasting performance. For best results, this professional-quality diffuser requires a minimum working pressure of 30 psi and should be used with CO2 pressure-rated tubing, not standard silicone tubing.
