I am having an issue with my GHL doser 2.1.

I use it as a stand alone unit to dose Carbon, Calcium, and Alkalinity supplements.

The doser is giving me a warning to "check filling level" on all three active pumps. However, there doesn't seem to be anything I can do to fix the warning, so the light is just blinking yellow, despite the unit dosing the aquarium. I have set the container levels and checked the calibration.

Essentially, the pumps are running, but they don't seem to recognize how much they are pumping, beyond the first 30-40 mls. I cannot reset this feature.

Any help here? I looked on the GHL forum but the site is difficult to read and navigate so I may have missed my answer.

Any suggestions are appreciated in advance.

Also, I have posted this in the Equipment forum and they recommended I come over here.
