When and how to dose 2part

[burtonboy182]

I am wondering if there is a better/ best or preferred method of doing 2part?
I have a apex, dos and trident
I’d like to not do the trident controlled dosing since I sometimes slack on replacing the reagents.
Should I dose Alk at night and Ca during the day
Split it up and dose alternating every hour?

I dose Calcium starting at midnight, Alkalinity at 3:00am

In my 45 frag system I dose esv 2 part. Alk first in the sump them Ca in the main tank.
I do this in the morning. I have been doing this for 2 years now same as iny 120 for 1 year untill I went to a carx with no issues and stable alk/Ca.
