- CO2 storage cylinder for all CO2 systems. Supplies aquarium plants with their main nutrient carbon dioxide (CO2) while preventing algae
- TÜV-tested, refillable 500g CO2 reusable cylinder (thread W 21.8 x 1/14). With pressure relief valve for safety
- Does not stand on its own. Requires a stand (JBL PROFLORA CO2 CYLINDER STAND) or a wall mount (JBL PROFLORA CO2 CYLINDER WALLMOUNT)
- Because CO2 liquefies under pressure CO2 pressurised gas cylinders must be in an upright position when in operation

-
Is it normal for the working pressure to fluctuate slightly and decrease towards the end of the bottle filling process?
Yes, this behavior is normal. The CO2 is liquefied under pressure in the gas cylinder. At 20°C, the pressure is 57 bar. If the contents decrease slowly and the temperature falls/rises, this can also affect the working pressure. Check the cylinder pressure, as the cylinder is probably almost empty.

Is there anything I need to bear in mind when handling CO2 gas cylinders?
Two points to note: 1) Bottle: Reusable bottles have a TÜV test stamped on them. This test must be renewed every 10 years, during which the bottle bases and the valve seal and screw connection are checked. 2) Carbon dioxide: Carbon dioxide is harmful depending on its concentration in the air. At a carbon dioxide concentration of 3-5%, breathing and pulse rates increase. Other symptoms include headaches, discomfort, and ringing in the ears. At carbon dioxide concentrations of 8-10% and above, these symptoms increase. This can result in cramps, fainting, respiratory arrest, and death by suffocation. A 500 g cylinder contains 500 g of CO2. This is equivalent to 11.36 mol (chemical unit of quantity). Under normal conditions (273.15 K, 101325 Pa), has a volume of 22.414 l, which means that 500 g of CO2 has a volume of 254.7 l. CO2 is heavier than air and therefore collects at the bottom. In a 20 m² room, this corresponds to a CO2 height in the room of 12.735 mm = 1.27 cm. When completely mixed with the air in a 20 m² room with a height of 2.5 m (equivalent to 50,000 l), this corresponds to a maximum gas concentration of 0.5% by volume, which is well below the level at which harmful effects occur.
-
Do the new JBL CO2 cylinders comply with the limited quantity (LQ) regulations in accordance with ADR?
Yes, the new JBL PROFLORA CYLINDER 500 U and 500 M fall under the special regulations for dangerous goods in limited quantities. This allows the pressurized gas cylinders to be shipped under simplified conditions in accordance with dangerous goods regulations, for a filling service or delivery by parcel service.
-
Can JBL PROFLORA CO2 products only be used for aquariums?
Yes, JBL PROFLORA CO2 products are designed exclusively for use in aquariums. The gas supplied promotes plant growth and can be adjusted with fine precision so that even the smallest quantities can be added to the aquarium. This ensures constant operation and the safety of the fish.
-
Pressure reducers for disposable and reusable bottles at the same time?
Yes, this is easily possible with the JBL PROFLORA CO2 REGULATOR. If you have the SET U, you can connect reusable bottles using the JBL PROFLORA CO2 ADAPT U - M adapter. This adapter is already installed in the SET M and can be removed with an Allen key. This allows the installation of JBL CO2 disposable bottles in sizes 500g and 1200g. An ideal option for bridging the gap between bottle refills or during vacation periods when someone else is looking after the tank
-
The pressure reducer cannot be removed
Your system is probably still under pressure. Close the cylinder valve and disconnect the CO2 hose from the pressure regulator. Open the adjustment screw and release the pressure remaining in the pressure regulator until both pressure gauges read 0 bar. Loosen the connection nut of the pressure regulator from the cylinder valve.
