How long is the cable of the pH sensor?
The cable has a length of 2m.

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 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 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.
-
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 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
-
What does the MIN date on the packaging mean?
All pH sensors (electrodes) are wear parts and are subject to natural ageing. JBL grants a 6-month guarantee if the sensor is put into operation before the stated MIN date. The purchase receipt serves as proof.
-
Is my sensor going to expire when we reach the date on the packaging?
No, don't worry. The MIN date on the packaging is not a BBD (best before date), but the date of the latest intial operation to guarantee 6 months warranty and 1 year operation. This information can also be found on the product packaging. Everything is therefore in order.
-
Why do brown stains form on the bottom after inserting JBL Manado Dark?
JBL Manado Dark is a natural product. This may initially lead to a slightly increased iron content and raised hardness values, which will normalise in the course of several water changes. In soft water a harmless iron efflorescence can occur. Rinse JBL Manado Dark briefly with tap water before use to remove any abrasion rubbed off during transport. _x000D_ _x000D_ If iron flowers (flos ferri) occur, you can rest assured. There is no danger for your invertebrates and fish. Plants absorb iron through their roots. You can siphon the iron flowers with a fine air hose, stir them into the soil and change 50% of the water every 2nd day for the first 10 days. This reduces the effect.
-
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.
-
There is a fuzzy, white organism on the JBL pH Sensor. What can that be ?
It is a harmless fungus which will disappear on its own after a while.
