and secure with union nuts.
CAUTION: The arrow on the check valve must point in the flow direction of the CO2, i.e. from the CO2 source to the diffuser!
[10]
• Connect hose to pressure reducer and secure with union nut. [11]
4.4 Connecting the CO2 flipper
• Rinse the flipper with warm tap water (do not use a cleaning agent!). [12]
• Moisten the hose connection and attach the CO2 supply hose. [13]
• In the aquarium, choose a dark place (prevents algae growth) with good water flow.
• Fix the flipper vertically at least 5 cm below the water level. [14]
4.5 Connecting the power supply
The integrated magnet valve makes it possible to control the addition of CO2:
4.5.1 with a time switch
This makes it possible to stop the CO2 supply during the night, as plants do not consume CO2 at night. Tip: Connect the
pressure reducer to the time switch, which also controls the lighting. [15]
4.5.2 Or with a pH controller
A pH controller such as the Dennerle pH controller Evolution measures the pH value in the aquarium on an ongoing basis
and regulates the addition of CO2 precisely and automatically via the CarboNIGHT pressure reducer. [16]
Switching states:
Power supply ON = LED ON = magnet valve open.
Power supply OFF = LED OFF = magnet valve closed.
Your CO2 fertilization system is now ready for operation.
5 Setting the CO2 quantity (bubble count)
5.1 The right amount of CO2
For lush plant growth, Dennerle recommends a CO2 content in the aquarium between 20 and 25 mg/l.
CO2 contents above 30 mg/l are not necessary for healthy plant growth and should be avoided in order to prevent unnecessary
stress for fish and other aquarium inhabitants.
The CO2 content can be determined with the CO2 long-term test (see 6) or by measuring carbonate hardness and pH value (see
6.7).
5.2 Setting the bubble count
One measure for the amount of CO2 supplied is the bubble count. The required bubble count depends on various factors, such
as the type of plants, the water flow and the illumination intensity. This is why it is necessary to calculate the amount of CO2
for each aquarium individually.
Rule of thumb for basic setup: Start with approx. 10 bubbles per minute per 100 l of aquarium water. For example, for a 200 l
aquarium, start with approx. 2 x 10 = 20 bubbles per minute.
Adjust the CO2 supply in small steps over several days until the desired CO2 content has been reached. Please note: The more
the water surface is moving, the more CO2 is driven out of the aquarium.
• Reusable CO2 bottles: Open the bottle valve slowly.
[17]
• Turn the control knob on the pressure reducer all the way in the „ + „ direction. [18]
• Wait until the first bubbles come out at the bottom of the flipper.
Note: The magnet valve must be open.
• Set the desired bubble count by turning the control knob in the „ + „ or „ - „ direction.
