Is your auto topoff working through siphon?? Looks like it is going to the
sump but I don't see any aqualifter or external pump on that clear tube.

There's a simple powerhead pump (Mini-Jet 606) inside the white bucket, resting
on the bottom of the kalkwasser solution.

A float switch, attached to the inside of the sump, turns the power on or off
for the powerhead (as water evaporates from the main system and then the sump
water level drops).
