Poll - Do you shut off your CARX at night?

[WhatCouldGoWrong71]

As the title says -

I am noticing a 4 hour swing. By 9AM I drift up .8 DKH by 1 it’s back in line. My lights are on at 10am. I’m curious if I shut my feed pump off from midnight to 6 AM if I would create more of a flat line.

I do not use one, but I would not shut off the flow through it ever. It risks any trapped water becoming anaerobic. Shutting off CO2 can be ok, IMO.
