Carbo Night M600

Dennerle CO2 fertilization systems are among the best CO2 systems in the world. They are impressive both because of their ease of use and because of their longevity due to their precision and quality of workmanship. The heart of all systems is the pressure reducer, whose job it is to reduce the bottle pressure to an adjustable working pressure. All three pressure reducers have the same, highly precise adjustment option - the "egg", as we call it at Dennerle. This adjustment knob regulates the amount of water added to the aquarium extremely precisely and, above all, slowly. Thanks to DVC technology (Dynamic Valve Control), sudden increases in the number of bubbles as with conventional needle valves and generally unwanted changes in the number of bubbles during operation are a thing of the past.
