Dennerle CO2 Night Cut-off Valve Comfort
For magnificent plant growth, DENNERLE recommends a CO2 content in the aquarium of approx. 20 mg/l.
As certain correlations apply between CO2 content, carbonate hardness (CH) and pH value, the CO2 content in the water can be calculated according to a simple procedure:
Measure the carbonate hardness of your aquarium water.
Read the pH value which corresponds to the desired CO2 content from the table. You should set this pH value +/- 0.1 by adjusting the number of bubbles accordingly. Example: Carbonate hardness 4 °d, recommended pH 6.8 +/- 0.1.
The procedure is even simpler with the DENNERLE CO2 long-term test Correct + pH.

Professional CO2 fertilisation for mini aquaria
Improves plant growth
Regulate the pH value of the water
Plants consist of almost 50% carbon. Thus CO2 carbon dioxide is the most important plant nutrient there is.
Aquarium water is nearly always deficient in CO2. Slow-growing, undemanding plants get by without an additional supply of CO2. Fast-growing and more demanding plants require additional CO2 fertilization for strong and healthy growth, however.
Dennerle is able to provide the right CO2 system for mini-aquaria, too, in the guise of the Nano CO2 complete set. For particularly lush aquascapes.
The latest result of the work carried out by the research and development department is a new, highly effective yet extremely compact CO2 diffusor designed especially for mini aquaria: The CO2 Nano Flipper.
Effective dissolving of CO2
Integrated bubble-counting function
- Incl. waste gas vent
How it works:
The CO2 bubbles issue from the opening at the bottom of the Flipper and rise along the channels. Part of the CO2 dissolves in the aquarium water in the process. The rest accumulates in the collector, from where it is released into the water. The safe design of the collector ensures that the small quantities of CO2 which are customary for nano aquaria are effectively dissolved, while undesired large quantities of CO2 are discharged automatically via the waste gas vent. The scope of delivery thus includes 2 collectors the smaller one for 10-25 l aquaria, and the larger one for 25-40 l aquaria.
The crucial advantage over the CO2 diffusors with ceramic membrane which are commonly used for nano aquaria is that the Nano Flipper does not produce any counterpressure. This means that it responds directly to changes on the pressure reducer. The required (small) quantity of CO2 required can thus be set reliably within a few minutes.
The CO2 Nano Flipper consists of highly transparent, break-proof plastic "Made in Germany" and can be combined with all standard CO2 supply systems. We recommend the Dennerle CO2 Nano Set. All CO2 hoses with an external diameter of 6 mm can be used.
Rule of thumb for the basic setting
Begin with approx. 1 bubble per minute per 10 l of aquarium water, which means approx. 3 bubbles per minute for a 30 l aquarium, for example.
The CO2 content can be checked most simply using the Crystal Line Mini CO2 long-term test. When the test shows a GREEN reading, the water contains exactly the right level of CO2.
The new Nano hose guide provides an elegant means of guiding the hose over the top edge of the aquarium without kinking.

The new Crystal Line range from Dennerle provides for lush and healthy plant growth in nano aquaria.
Chemically refined and aesthetic products ensure a reliable supply of valuable CO2 for small aquaria.
The basic set comprises a disposable CO2 cartridge and the pressure reducer with precision control valve.
Crystal Line is a comprehensive range of products covering all aspects of CO2 fertilization for small aquaria. A convenient 80 g disposable cartridge serves as the source of CO2.
The specially developed Nano pressure reducer ensures exact dosage of the amount of CO2 supplied. With its newly designed precision control valve it defines new standards in setting accuracy and constancy of supply.
Even the most minimal quantities of CO2 in the order of only a few bubbles per minute can be dosed with precision.
The elegant diffusors are hand-made from crystal glass.
The check valve, the bubble counter, the diffusors and the CO2 long-term tests from the Dennerle Crystal Line have been designed to complement the aesthetics of nano aquaria.
All the products are made of high-quality crystal glass and are individually hand-crafted. For the first time, the technical components no longer need to be hidden away, instead underscoring the style of design-oriented aquaria.
Crystal Line Nano CO2 Set, includes CO2 base, 80g CO2 disposable bottle and Nano Pressure Regulator.
