For highly efficient dissolution of CO2 by nano-diffusion

– Diffusion regulation thanks to the integrated bubble counter
– Also suitable for bio CO2 systems
– Made of high-quality, transparent acrylic material
– Very compact shape – can be installed "invisibly" in the aquarium
– With suction cup
– For 4/6 mm tubing
– Before use, mount it vertically in the aquarium for a few hours so that the diffuser fills with a little water.

Under the name "CO2 Diffuser Ultra," Dennerle offers a range of modern CO2 diffusers. Made of transparent, shatterproof acrylic, these diffusers are safer than conventional glass diffusers and ideal for children's aquariums. Their ultra-compact design allows for discreet installation within the aquarium using the included suction cup, or their attractive design makes them easily visible.

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

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

The CO2 Diffuser Ultra S is suitable for aquariums up to 100 L and is particularly well-suited to nano aquariums, which are very popular. The M model is suitable for aquariums up to 200 L, and the L model for aquariums up to 400 L.
