The retaining spring in the check valve fits very tightly and ensures that no water can return. Therefore the air pressure of a diaphragm pump or our breath is not strong enough to open the spring. The valve can be opened by the pressure of the ProFlora bioCO2 systems and also the m and u series. Check valves used in air systems have a smaller counter-pressure and are also part of the JBL range.
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.
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.
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.
