No Alk drop

[Ocean’s Piece]

Just tested my Alk and I noticed it hasn’t changed from my weekly dose last week (setting up a doser, but I dose weekly with a syringe). I have heard things about corals just not taking in Calcium and Alk sometimes and I was wondering why this happened.
My best guess is that I just added 5 new corals on Saturday, one SPS, three LPS, and one softie. Is this normal?

Update: No Ca drop either. I assume no Mg drop either but I dosing mg is more of when I feel like (about twice a month) it since it’s consumed so little lol

If alk is not being consumed, there no way for calcium or magnesium to be significantly consumed.

New arrivals might have irritated existing corals a bit. I'd just keep watching them.

Do the existing corals look OK?

Yes, nothing wrong. Everything extending as usual.
