The working pressure on the pressure gauge does not change
When you adjust the working pressure, the CO2 addition needs to be running actively, otherwise the change will not be immediately visible in the event of a reduction. An increase is also visible without running CO2, but not immediately. That’s why you need to ensure that CO2 is added during the adjustment process for every reduction or increase.
-
Is it normal that the working pressure fluctuates minimally and decreases towards the end of the cylinder filling?
Yes, this behaviour is normal. The CO2 is liquefied under pressure in the gas cylinder. At 20° C it is 57 bar. If the content decreases slowly and the temperature drops/rises, it may also have an effect on the working pressure. Check the cylinder pressure, as the cylinder is probably almost completely empty.

Is a special action necessary when using CO₂ compressed gas cylinders?
Please note two important points: 1) Cylinder: Reusable cylinders are TÜV tested and this is stamped on the cylinder. This test needs to be renewed every 10 years, with the bottom of the cylinder and the valve sealing and threaded joint being tested. 2) The carbon dioxide: Depending on its concentration, carbon dioxide is harmful in the air. The respiratory rate and pulse rate increase at a carbon dioxide concentration of 3-5%. Other symptoms are headaches, discomfort and ringing in the ears. Carbon dioxide concentrations of 8-10% and more cause these symptoms to become more pronounced. This may lead to cramps, fainting, apnoea and death from suffocation. One 500 g cylinder contains 500 g CO2. This is equal to 11.36 mol (chemical substance amount unit). One mol of a gaseous substance has a volume of 22.414 l under normal conditions (273.15 K, 101325 Pa), so that 500 g of CO2 result in a volume of 254.7 l. CO2 is heavier than air, so that it collects on the ground. This corresponds to a CO2 height level in the range of 12.735 mm = 1.27 cm for a room of 20 m². If it is mixed completely with the air in a room of 20 m² and a height of 2.5 m (corresponds to 50,000 l), this corresponds to a maximum gas concentration of 0.5 volume %, which is well below the dangerous level.

Should I use several check valves on my CO2 installation?
True to the motto, better safe than sorry, some aquarists install several check valves in the same circuit. For example, if you use the JBL PROFLORA direct inline diffuser or the JBL PROFLORA CO2 Count Safe bubble counter, you already have an integrated check valve. If you also use a separate check valve (JBL PROFLORA SafeStop), there may be problems with the opening of the check valves. This effect can be observed if, after the night switch-off or interruption of the supply with the controller, the addition does not restart automatically. Please note that, depending on the working pressure and the number of bubbles, a few minutes may pass between the start of the supply and the visible entry of CO2 into the aquarium. Each spring in a check valve needs a certain pressure to be opened. Several springs can therefore interfere with each other and, depending on the distance between the two check valves, reduce the pressure at the spring to such an extent that it remains closed. Therefore, please always use only one check valve for your CO2 installation.

The pressure reducer cannot be removed
Your system is probably still under pressure. Close the cylinder valve and remove the CO2 hose from the pressure regulator fitting. Open the regulating screw and release the pressure still present in the pressure regulator until both pressure gauges show 0 bar. Loosen the connecting nut of the pressure regulator fitting from the cylinder valve.
-
Is 1.2 bar working pressure sufficient for my CO2 system?
For a long time JBL CO2 pressure reducers had a preset working pressure of 1.5 bar. This has become established in people's minds. With the new JBL PROFLORA CO2 pressure reducers with pressure gauges, the working pressure is set to 0 bar on delivery. You admit CO2 via the large adjustment knob for the working pressure and turn it until the desired working pressure is reached. Approx. 1.2 bar is the maximum setting here. A minimum of 0.6 bar is required for the operation of all JBL non-return valves or backflow protections. This ensures that the check valve opens. A higher working pressure is not necessary, which is why all the accessories also work with the JBL PROFLORA BIO SETs. A lot of CO2 accessories available on the market give very different specifications for the working pressure. To be on the safe side, the standard of 1.5 bar which is common on the market is mentioned. As a rule, the working pressure required is the same as that on which the JBL PROFLORA CO2 accessories are based. Only a few exceptions require a working pressure of over 2 bar and are very special technical components.
-
Is a tool needed to adjust the CO2 quantity?
No, a tool should never be used. The use of a tool can lead to damage. There is a thin spike at the tip of the needle valve. If the needle valve is closed clockwise and turned too tightly or with a tool, it may break off and damage the pressure regulator.
-
Do you need a tool to assemble the pressure reducer?
No, a tool is not required and should not be used under any circumstances. The use of a tool can lead to damage. You can mount the pressure reducer on the CO2 cylinder with your hands. Turn only until you feel resistance and then turn about half a turn more. This way the pressure regulator fitting is hand-tight. A short hissing sound will be heard when attaching the fitting to disposable cylinders.
