Could also be what salt is being used. I have a buddy who couldn't get the dkh he needed with reef crystals, changed to dnd salt and it instantly went to where he needed it.
When did you switch to Kent and how many times have you done pwc? Your calcium reactor might be affecting it.
I dose alk and cal daily 40ml of both. Alk 9.8-9.1 cal 400 sometimes I dose more cal to raise it. If you are lps or softie heavy your alk will lower quicker. I would dose two part like you been and when you test keep a log of how much you add and how the reading go up. Test daily until you figure out how much is needed to maintain proper levels then test bi weekly. I use kent salt alk is 9.1 and I have to dose. Things grow!!!!!
Alright so here is my water now. At 1.025 SG i have my pH at 8.1, kH=5.9, calc=420, mag=1280 (this is an hour after the lights turned off)
My freshly mixed water in the bin before i added it to the tank was
At 1.025 SG i had my
PH 8.2
KH 8.7
Calc 460
Mag1320
What should I do now? Been like weeks that my KH keep changing from 8 dkh and to as low as 4.3dkh

How would I determine how much to dose? I have dosed before and then stopped because i wasn't sure if i was doing it right. Do I dose gradually and increase the amount day by day? Or I have to dose an initial or starting amount (like 25 ml) and Then just a maintenance amount (maybe 5ml) everyday ?
Any where between 8-12. Stability is key, my lfs looks for around 10.5 in there tanks. Mine is 9.1-9.8. When my acans started to melt it was 5.6 they fully recovered and I'm seeing good growth in corals and clams.
