Under the name “CO2 Diffusor Ultra”, Dennerle offers a series of modern CO2 diffusers. These are made from transparent and unbreakable acrylic. Therefore, they are safer than conventional glass diffusers and perfect for children's aquariums. Thanks to their ultra-compact design, they can be installed "invisibly" in the aquarium with the included suction cup or also in the field of vision thanks to their attractive design. 

The newly developed membranes are specially sintered with extremely small porosities. The resulting nano-diffusion of CO2 ensures very effective and safe dissolution of this essential nutrient for aquarium plants. With the help of the integrated bubble counter, the amount of added CO2 can be easily controlled.

The CO2 Diffusor Ultra is compatible with standard CO2 systems, e.g., with the disposable or refillable Dennerle Carbo START, Carbo POWER, and Carbo NIGHT systems. Due to the much lower operating pressure of around 0.3-0.5 bar compared to conventional glass diffusers, the CO2 Diffusor Ultra is also ideal for bio CO2 systems. The hose connection fits all standard 4/6 mm CO2 tubes, e.g., with the special CO2 tubing from Dennerle. 

The CO2 Diffusor Ultra S is suitable for aquariums up to 100 L and especially for the highly popular Nano aquariums. The M model is suitable for aquariums up to 200 L, and the L model for aquariums up to 400 L.
