Alk question

[Patpare]

Does alkalinity fluctuate from day to night?light on/lights off
I'm asking this question because with my work schedual lately I'm only able to test when my lights are off in the morning.
Thank you

No. Assuming no additions of any kind, alk is just declines. It may decline faster during the day, but never rises.
