Vertex skimmer overflowing?

[Red Coral Aquariums]

How long has your vertex been up and running?
Could you do a PH reading first thing in the am. to see if there is an abnormal swing?
Do you shut off any flow pumps at night?
How long after your lights shut off does it start to overflow?

It's been running for a couple weeks
Pumps are on 24/7
It happens overnigt so don't know when it happens exactly
I will try to run the skimmer with drier skimmate and see what happens

Is the effluent opened all the way? If so, try raising the skimmer a little in the sump, the ATO level may be just a little too high.

i have the same problem, it seems like the skimmer with create not alot of bubbles and then all of the sudden it will just kick in and work again and create lots of bubbles and then it over flows, my skimmer water level is always constant and it happens when im away from work. so no feeding is done. i had 5 days of great skimmate and just when i was going to empty it after work bam, all back into the tank this is the second time it happens to me, only had it for 2 weeks so maybe break in period. but i have no idea either. i have no idea what the reason for it is though. nothing changes in my tank from when it works and then it overflows.

I'd take the pump apart and inspect everything including the volute. Apart from that it could be that changing barometric pressure at night is driving the water level in your sump UP which the ATO would be powerless to stop.
