JBL PROFLORA CO2 ADVANCED SET U
Item no. 6463100
Product features
- Ready-to-connect CO2 fertiliser system with solenoid valve for night switch-off. Provides the ideal supply for all aquarium plants in freshwater aquariums from 40 to 600 l while preventing algae
- Simple assembly: screw the pressure reducer with its mounted solenoid valve onto the cylinder, connect the hose with the bubble counter/check valve and reactor. Plug the solenoid valve into the timer (not included), set the bubble count - done
- Disposable storage cylinder. No hose slippage thanks to hose screw connections, check valve prevents water from entering the cylinder. Pressure gauges show cylinder and working pressure
- The correct CO2 concentration in the aquarium water is checked via the display of the CO2/pH permanent test included and can be readjusted if required
- Contents: 500 g disposable CO2 cylinder, pressure reducer with solenoid valve, 3 m hose, bubble counter with check valve, TAIFUN CO2 reactor + extension set, CO2/pH permanent test with reagents

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: _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_

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. _x000D_ 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.

What is the minimum working pressure I need to use the JBL CO2 accessories?
All check valves or backflow protectíons from JBL require a working pressure of at least 0.6 bar for the valve to open. This feature can be found in the JBL PROFLORA CO2 TAIFUN SAFESTOP, COUNTSAFE and INLINE. The JBL PROFLORA TAIFUN diffusers also all already work with this pressure. A higher working pressure is not necessary, which is why all accessories also work with the JBL PROFLORA BIO SETs (except JBL PROFLORA CO2 STARTER BIO SET). Due to installation, a slightly higher working pressure than 0.6 bar may be necessary due to long hoses and other components, which is why the presetting of 1.2 bar is sufficient in any case.
-
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.
-
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.
-
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.
-
What do you have to consider when changing networks in the home network?
Under " current network", the network to which the controller is currently connected is displayed. If the controller is to be integrated into another network, the old network must first be left. To leave, press and hold " current network" and confirm with "Yes".
