Alk swing

Will alk swings begin to kill corals

Depends on how big of a swing, what types of corals, and the nutrient levels.

SPS corals in a low nutrient environment seem more sensitive than most other corals.

That isn't a swing (which, IMO, implies up and down frequently), that's just a decline and won't kill corals.
