Just checked... 37. I dont know why it seems so hard for me to get it to stay at 35. It's consistently 36 and on a slow climb all the time. Thanks to this thread, I've started adjusting by pulling 500ml 4x (over 24 hrs) and replacing with 0 ppt ATO. I do this from time to time as needed. It's a 250 liter system. And I dose AB @ 30ml/day.

You must be dosing a lot of two part. I had the same issue until I switched to carx.

Maybe. I don’t know actually. Is this a lot for a 250 liter system?

Part A: 30ml/day. Part B: 30ml/day
Alk: 8.5 - 8.9 (currently)
Ca: 380

Yep, definitely can accumulate without water changes.
Sodium Carbonate + Calcium Chloride = Salt + CA + Alk (kinda)

And if you do magnesium also:
Magnesium Chloride
Magnesium Sulfate
Which BRS and I think a lot of people do at 3:2 ratio.
There are concerns that sulfate can accumulate.

I dose 80 ml/day of each, in a 240G display tank.
So you are in range of what I do.

Check your magnesium levels if you suspect you are using too much.
Especially if you see sudden shifts like it looks on your graph.
