Did it ... AGAIN

[gregzz4]

must remember to plug ATO back in after messing with tank

This is the second time this month I've left it unplugged for a couple days
Thankfully it only drives my Sg up by 1 point - loses 3 gallons/>3% in 2 days

Think I'll rig a new LED for a low sump level, or a float and alarm. After all, I am getting older
