Dennerle - CO2 Diffusor Ultra

Dennerle CO2 Diffuser Ultra – Effective CO2 distribution for lush aquarium plants

Give your aquarium plants optimal growth conditions with the Dennerle CO2₂ Diffuser, a high-quality and modern solution for supplying carbon dioxide to freshwater aquariums. This diffuser belongs to the latest generation of add-on units from Dennerle and is equipped with a specially developed ceramic disc that atomizes the CO2 into ultra-fine bubbles - for maximum absorption and efficiency.

Thanks to the nano-atomization technology, an even and effective distribution of CO2 in the water is ensured, which contributes to healthy plant development and improves the overall water quality.

The diffuser is made of high-quality, crack-resistant acrylic, which not only makes it robust and durable, but also gives it a stylish and discreet design that blends into all types of aquarium environments.

A built-in bubble counter makes it easy to monitor and adjust the CO2 dosage in real time, which is particularly practical for those who want to have full control over their CO2 system. Fits standard hoses with an inner diameter of 4 mm (outer diameter of 6 mm).

Available in three sizes to suit aquariums of different sizes:

Small – for aquariums up to 100 liters

Medium – for aquariums up to 200 liters

Large – for aquariums up to 400 liters

Whether you are a beginner or an experienced aquarist, the Dennerle CO₂ Diffuser is an excellent choice to take your planted aquarium to the next level.
