14 is where most Corals die some earlier.
Didn’t read how you’re dosing alk and ca...
My tank recently went out of wack too but over the 2 year mark.
If your manually dosing ca and alk I would dose ca only and not dose any alk, test every other day and watch the alk slowly go down to 8ish.
As you bring up the ca it should stabilize the alk.
