How can I remove the hose from the device?
At first the air hoses and special CO2 hoses can easily be pushed on the connection piece. The hoses harden more and more as the months go on and can only be removed from the connection piece using great force. If you pull the hose hard it will only strain the connection, which could, in the worst case, even break off. Instead cut the hoses you want to remove laterally at the ends and carefully remove them. For this it’s always advisable to install hoses with some reserve in its hose length.
Why does the CO2 diffuser create large bubbles?
In order to enable the modern ceramic PE hybrid membrane to build consistent micro bubbles and to ensure an effective
CO2 spread in the water, it needs to be soaked in water for approx. 24 hours before being put into operation. Do not, therefore, switch on the CO2 supply after installation until the period of time mentioned has passed. Alternatively you can put the membrane into a bowl of water. Without this soaking the pores will not have enough water and will let large bubbles pass with an uneven distribution.
I can hear the CO2-INLINE-DIFFUSOR whistling / chirping
In this CO2 diffuser the CO2 gets pressed through a fine diaphragm. Depending on the counter-pressure, this sometimes causes a slight chirping sound. If the sound intensifies during operation this indicates a soiling of the diaphragm or change in the operating pressure. Please clean the diaphragm and reduce the operating pressure, if required.
Can the inline diffuser be used in a bio-CO2 system?
We wouldn’t recommend installing the JBL ProFlora Direct in a bio-CO2 system. The working pressure is not big enough to achieve an even addition of the CO2. Moreover, there is a danger that the pressure will not be able to escape through the integrated check valve, and this can lead to damage in the reaction vessel, if it isn’t able to withstand the pressure.
Why does my CO2-INLINE-DIFFUSOR need more bubbles per minute than my old CO2 reactor/diffuser?
The size of the bubbles is essential to providing compatibility. That’s why you cannot compare the number of bubbles in the ProFlora direct with the old method of determining the bubbles (e.g. with the ProFlora Count (safe) or other bubble counters). Depending on the method used, the bubble size can differ by up to 300 %. That’s why it’s important to use the same bubble counter when comparing both systems in order to determine the conversion factor “bubble number in the old bubble counter” to “bubble number in the ProFlora direct”. Since there is no standard CO2 bubble size, it is otherwise difficult to determine the true conversion rate.
The check valve doesn’t seem to let CO2 pass through it. What can I do?
Please wait until sufficient pressure has built up in the CO2 hose. Alternatively you can sharply increase the CO2 supply for a short time.
The bubble counter doesn’t fill with water. What can I do?
If there is no water in the bubble counter after the installation, just wait a few hours before switching on the CO2 supply. The water jet of the filter will then cause water to enter it. Alternatively while installing it, you can fill the chambers of the bubble counter with water.
Is my SafeStop damaged if I can’t blow through it?
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.
