My Octo KS-100 Kalk Stirrer uses gravity to dose.
It is remotely installed behind a wall (right behind the tank).
The tube goes through a hole in the wall that is slightly below where it enters the cabinet and gets to sump. This means there is a short uphill before the downhill to the tank.
I believe this causes an air lock and backs up the whole system.
Because the tank is already in place I'd prefer not to drill new holes that better align.
I already tried increasing the tube size from 1/4" to 3/8", but that was a fail.
I will try raising up the doser higher to increase gravity pressure.
Any other ideas on how to overcome this issue?

my experiences with airlocks in my gravity fed system
how I learned to mitigate airlocks in my system,, tho some jiggling is always required when the lines have run empty
