The water is disappearing from my bubble counter – where’s it gone?
The bubble counter with integrated check valve JBL PROFLORA CO2 Count Safe has a check valve on the inlet side into the container. It is located on the IN side with the riser pipe. This prevents water from getting out of the bubble counter in the direction of the CO2 bottle or other attachments in front of it.
For the start-up and after each cleaning, fill the bubble counter with water up to the mark (fig. B in the instructions for use). During operation, the water level in the bubble counter may fluctuate, depending on the amount of CO2 added. A large number of bubbles with high working pressure can cause the water to be displaced from the chamber. It is important that the bubble counter is not installed at an angle so that water can run out. Normally, the water level remains unchanged and should be checked weekly.
Once CO2 stops entering, the water from the aquarium will return to the bubble counter with a time delay. In the bubble counter, the water flow is stopped by the check valve at the inlet (IN). There is therefore no cause for concern. You can quickly detect a defective check valve yourself by noticing water in the hose between the CO2 cylinder and the check valve. Please also refer to the FAQ on the use of two check valves at the same time.
