Umbrella and other softie white spots

[jwoyshnar]

Hello all, i have these white spots on my corals and was hoping sopmeone could help me out with them. All parameters are where they should be. 0 ammonia 0 nitrates. These white spots have been spreading but only to my umbrella and my 2 devils hand corals.

Anyone?

I think i may have solved my problem here. I think i have a bacterial infection on several corals. I recently just switched to a controllable wavemaker that shuts down at night. That was a week ago. i just read elsewhere on here that shutting off flow at night can cause this. Now how do i treat the infected corals?
