I'm curious to know what salt you are using and how you are measuring salinity and alkalinity.

I never added ALK and I use Red Sea Coral salt which is 12dkh. I may be switching to Fritz’s reef salt. But may have issues dosing micro nutrients not having test kits for those.
I use a lot of Red Sea products. Red Sea also have another salt but mag and calcium are much lower but I may have to deal with that over higher ALK levels

Generally it’s recommended to use salt mixture with parameters close to those you want to keep. If you would like to keep your dKH around 9, I would recommend to use salt mixture closest to that. It is generally easier to use salt with slightly lower alkalinity and then supplement it , than use salt with higher alkalinity and lower it or wait for corals to consume it.

I'm not sure what you mean by micronutrients (that's not really a seawater/oceanography terminology) but I would not dose nutrients without either a measurement, or an indication from an organism that it was suffering and you had strong reason to believe a specific element was needed.

I meant to text trace elements.
As far as calcium and magnesium my corals absorb a lot so I didn’t want to switch sea salt
