Alkalinity dipping

[haitian_reefer]

Anyone know why my Alk is dipping at night? Should I dose more to compensate and avoid the dip?

The graph tells nothing since it has no x or y axis scale.
When do you dose alkalinity?

Thanks for the response. I am dosing 0.7 every 3 hours. Here is screenshot of the schedule.
