HELP! Montis dying off

[Sandroni]

I was finicking with the light schedule a tad and I feel like the months didn't take to the change very well. I used Red Sea Pro salt and water change 10% 1 a week. Any ideas? Salinity 1.025-6
Thanks,

If it was the light, then it was the lights. What did you do, exactly? I would not change anything else because of this.
