9.2. Measurement/Maintenance
- The tip of the probe must be continuously submerged in the solution while measuring.
- A new probe or one that has been dry for a longer period has to lay in water for at least 24
hours.
10. Malfunctions
- The unit indicates incorrect values --> calibrate the probe.
- The probe cannot be calibrated:
--> check glass probe for damage
--> check the content of electrolytes on the refillable probe
--> replace the probe (average probe lifespan is 1 - 3 years).
11. Set up of a complete pH-control system at the aquarium
With the pH-computer, a complete pH-control can be realized at the aquarium. For this, you need
in addition to the pH-computer an Aqua Medic solenoid valve and CO
steel bottle for CO , the pressure regulator regular, the bubble counter and the CO
2
CO into the aquarium .

The CO unit is mounted following the instructions. Between the CO
2
the solenoid valve is mounted close to the pressure regulator. The solenoid valve is inserted into
the connection plug of the pH-computer. The computer is programmed and calibrated, following
the instructions. The pH-probe is fixed in the aquarium at a dark and good circulated place. As
soon as the pH in the aquarium raises above the adjusted set point, the computer opens the
solenoid valve and CO
If the adjusted set point is reached, the solenoid valve closes and the CO
adjustment of the needle valve at the pressure regulator should not be at a too high bubble count.
It should be adjusted in a way that even if the solenoid valve fails (e .g. due to clogging by dirt)
the pH-value in the aquarium does not decrease to critical values.
