Dennerle CO2 Diffuser Ultra S

Under the name "CO2 Diffuser Ultra," Dennerle offers a series of highly advanced CO2 injection devices. The diffusers are made of transparent, shatterproof acrylic, making them significantly safer to handle than traditional glass diffusers and ideal for children's aquariums. Their ultra-compact design allows for "invisible" installation in the aquarium using the included suction holder. Even in visible areas, they do not disturb the overall appearance thanks to their attractive look.

The newly developed membranes are made from a special sintered material with extremely small pores. The resulting nano-misting of the supplied CO2 ensures highly effective and safe dissolution of this essential plant nutrient in the aquarium. With the integrated bubble counter, the amount of CO2 being added can be easily monitored at any time.

The CO2 Diffusers Ultra can be combined with all common CO2 systems, such as Dennerle's single-use and multi-use systems Carbo START, Carbo POWER, and Carbo NIGHT. Due to the significantly lower operating pressure of approximately 0.3-0.5 bar compared to classic glass diffusers, the CO2 Diffusers Ultra are also ideal for bio CO2 systems. The hose connection fits all standard CO2 hoses with a diameter of 4/6 mm, such as the Dennerle CO2 special hose.

The CO2 Diffuser Ultra S is suitable for aquariums up to 100 liters and is particularly popular for nano aquariums. The M model supplies aquariums up to 200 liters, while the L model is designed for aquariums up to 400 liters. Before use, it should be mounted vertically in the aquarium for a few hours to allow the diffuser to fill with some water.
