Dkh is high. I'd do water change Should be 7-12 dkh ...

I’m typically a slow-as-you-go type of person with the tank. However, your alk is burning high. It’s damaging! So I personally would start with a 50% change to get it down to something less “burning.” I say this with ignorance because I’ve never had 19dKH, but that is coral-damaging high. After this change, I’d go with a 10 – 20% change until your numbers are more reasonable.

+1 to what redfishbluefish said. When your alk gets to high you will start to burn your corals, especially new growth.
