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.

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.
