FAQ
I have a deviation between the manual pH measurement (measuring tape, colorimetric measurement or Photolyser) and the display in the measuring and control device.
- Error in colorimetric measurement with phenol red indicator (deviation up to 0.4 pH) due to salt

The pH value of the device differs from the manual measurement
- Incorrectly performed manual measurement
- Probe dirty or aged

My AquaCat does not climb walls
- Filter bag full
- pH value is too high
- Biofilm on walls
- Device too heavy (AquaCat 3000 and Viking TURBO)
- Drive belts loose

An "Alarm" LED is flashing on my measuring and control device, and/or the display "Sample water alarm" or "Sample water error", the dosing is interrupted.
- The sample water monitoring in the flow valve has responded.
