Bleached lobophyllia

[Reefnate]

I am wondering if I managed to accidentally kill my berghia. user error on calc dosing left it way low. Like 210. Raised to 420 over period of two weeks. Haven’t seen a berghia since. Hoping beyond hope that I didn’t kill them without consideration. Thoughts?

225. 6 AI prime. sg 1.023, nitrate near zero, alk 8.3, calc 420, ph 8.2.

Oh and I now have a lobo that’s bleached out. It has to be a sign of something
