-
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: _x000D_ _x000D_ 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. _x000D_ _x000D_ 2) The carbon dioxide: _x000D_ Depending on its concentration, carbon dioxide is harmful in the air. _x000D_ 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. _x000D_ _x000D_ 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._x000D_
-
Which CO2 cylinders are compatible with the JBL PROFLORA CO2 SET V?
You can use all CO2 pressurised gas cylinders offered for aquaristics in specialist shops. You have the choice between disposable pressurised gas cylinders with thread M10x1 and reusable pressurised gas cylinders with thread W 21.8 x 1/14. An adapter for reusable cylinders is already included in the set.
-
May the JBL PROFLORA CO2 products only be used for the aquarium?
Yes, the JBL PROFLORA CO2 products are designed exclusively for use in the aquarium. The gas contained promotes plant growth and works with fine precision so that even the smallest quantities can be supplied to the aquarium. Constant operation and the safety of the fish are thus guaranteed.
-
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.
