The Dennerle CarboNIGHT FLEX400 set is a starter set for a successful CO2-supply in the aquarium. It consists of the CarboNIGHT precision pressure reducer, adapter for reusable CO2-cylinders, special non-return valve, hose, Flipper addition device and a long-term test to determine the CO2 content.
The choice of CO2-cylinder is entirely up to the operator, as the adapter allows the use of both reusable and disposable cylinders. The powerful CarboNIGHT pressure reducer is equipped with a solenoid valve for night shut-off, to protect aquatic plants and all living organisms in the aquarium and to maintain the vitality of all. The Dennerle Flipper made of Macrolon, which can be used in aquariums with a volume of up to 400 litres, provides a successful addition. The glass endurance test can be used to constantly check the current CO2 content. This can be filled with Aqua Rebell CO2 Check, for example.
