Product features
- Regulates the addition of CO2 for perfect plant growth in the aquarium and the ideal pH value for aquarium fish
- Connect temperature sensor, transformer and pH electrode (not included), connect to the solenoid valve, enter the wished pH value or use the automatic programme
- Touch display enables easy operation through the operating menu. For automatic adjustment of CO2 addition, the carbonate hardness (KH) needs to be measured and entered.
- The programme calculates the ideal pH value from the KH and the existing pH value and adds as much CO2 as necessary until the pH value is reached. Also displays the water temperature
- Package contents: CO2 control unit with touch display, wall bracket, power supply unit, temperature sensor + suction holder, connecting cable to the solenoid valve, cuvette holder for calibration liquids

What does DELTAV mean in the display?
This message indicates that the potential difference per full pH unit is smaller than 30 mV. The pH sensor is either too old, defective or was accidentally calibrated twice with the same buffer solution. _x000D_ _x000D_ Remedy: Repeat the calibration and take care to use the buffer solution correctly. If this does not work, connect a new sensor and calibrate again.
-
What does the message INSTAB mean?
The message INSTAB indicates: instable sensor voltage: the sensor tip is dirty, the electrolyte has leaked from the sensor, the sensor tip is damaged. _x000D_ Remedy: Clean the sensor head (see the respective instruction), put the sensor into the storage solution for 24 hours and repeat the calibration. If this does not work the sensor is defective and should be replaced.

What deviations during the calibration are usual and how are they connected to the temperature?
It is difficult to give a precise answer without information about the sensor, particularly the age of the sensor. Good sensors have deviations in the range from 0.02 to 0.05 pH levels when calibrating. _x000D_ _x000D_ The input voltage differs for each sensor, as each sensor has its own individual properties. For the majority of our sensors, it is between -30 and +30 mV at pH 7. _x000D_ _x000D_ Both input voltages (pH 7 and pH 4) are important when assessing the quality of a sensor. The greater the difference between these two values, the better the sensor and the precision of the measurement and control. The differences should be over 140-150 mV. _x000D_ _x000D_ The temperature sensor should always be used during calibration. The pH level varies according to temperature, so that it is always best to measure the pH level with temperature compensation. The deviation is between 20 and 30 °C, 0.17 pH levels, and the relationship is nonlinear.

How often does the JBL pH/CO2 Control have to be calibrated?
In the menu you have the chance to choose the interval before the next calibration reminder. The following calibration intervals are available: _x000D_ 30 days _x000D_ 45 days _x000D_ 60 days_x000D_ However it is highly recommended not to select the 60 days setting, since each pH sensor wears continuously and the measured values become subject to change. Thus the more often you carry out a calibration the more reliable are the measurement results.
-
Why does the controller permanently indicate a too high/low pH value? And why doesn’t the calibration work although the sensor is new?
The cause can probably be fixed quite easily. The protective cap of the pH sensor needs to be removed before insertion into the aquarium / before the calibration, to carry out control / calibration correctly. The protective cap serves as storage and “reactivation” of the sensor with the storage liquid. It has to be removed for use inside the aquarium and during the calibration because no water from outside can pass through. _x000D_ _x000D_ If the controller still displays an error, even after the removal of the protective cap, please read the FAQ with the several error messages in detail. _x000D_
-
What does the message OFFSET mean?
The message OFFSET indicates: The sensor voltage at pH 7.00 is outside the limit value, the sensor is too old, the cable is defective, no sensor is connected or the calibration has been performed with buffer 4 solution. _x000D_ _x000D_ Remedy: Check the sensor cable for any signs of damage and repeat the calibration. Take care to use the buffer solution correctly. If this does not work, replace the sensor and calibrate again.
-
Do I need a night switch-off when I use the JBL Proflora pH Control Touch or the JBL PROFLORA CO2 CONTROL?
You need a separate soleniod valve (JBL ProFlora v002 or JBL PROFLORA CO2 VALVE) to control the CO2 supply. A further night switch-off for CO2 systems, controlled by a pH control unit is not needed, as the CO2 supply will not be turned on in the absence of CO2 consumption, or it will happen less frequently when CO2 degassing occurs at the water surface. That is why the control units do not need a timer
-
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.
