Which level sensor numbering is correct?

In your videos section it appears two videos contradict each other on the numbering of level sensors. Could you please confirm which is correct?

Thanks, Brian

Hello Brian,

the first video with one senor (ATO) should be correct: 5/6 lower and 7/8 upper ports.
I will forward this for a review.

Thanks!

If the one sensor (ATO) video is the correct numbering, then the auto water change video is also wrong.

Thank you for bringing this to our attention.
It is fixed now! :)
