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
pressure regulator regular, the bubble counter and the CO
The CO unit is mounted following the instructions. Between the CO
2
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
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.
