The Dennerle CO2 Diffusor Ultra ensures highly effective CO2-dissolution through nano-atomisation. The diffuser is made of high-quality transparent acrylic. It can, therefore, be used almost invisibly in the aquarium. The newly developed membranes are made of a special sintered material with extremely small pores. The resulting nano-atomisation of the supplied CO2 ensures a highly effective and safe dissolution of this important plant nutrient in the aquarium. With the help of the integrated bubble counter, the amount of CO2 added can be easily controlled at any time.

The CO2 diffuser Ultra S is suitable for aquariums up to 100 L and is therefore particularly popular for nano aquariums. The M model supplies aquariums up to 200 L, the L model aquariums up to 400 L.


  • Controlled supply through integrated bubble counter
  • Also suitable for Bio CO2-systems
  • Made of high-quality transparent acrylic
  • Ultra-compact form
  • With suction holder
  • For hoses 4/6 mm


Before use, mount vertically in the aquarium for a few hours so that the diffusor fills with some water.



Dennerle has been operating in Vinnigen since its foundation in 1966 and, after more than 50 years of company history, the building blocks Dennerle relies on is experience. The philosophy behind Dennerle is to create a small and tangible, intact piece of nature, in harmony with the natural environment. That is why sustainability is a company-wide concept and is implemented at every possible point. In order to achieve an ecologically balanced aquarium, Dennerle relies on a system that is based on 5 pillars. Animals, plants, water, substrate and lighting. Dennerle offers the optimum equipment to bring this complex, but not complicated system into harmony.
