Bubble bleaching?

[MohrReefs]

When I bought it, it was egg shell white. It then turned pinkish brown when I brought it home, but has these white sections on the bubble.

Was it bleached and it's now healing or is it currently bleaching?
Feeders come out at night, other than some recent stress due to a demonic goby with space issues it's been relatively happy.

Looks good to me.

Looks normal, just a little unhappy. Moderate light and flow, occasional feedings and salinity of 1.025=1.026 and Ph range 8.1 - 8.3 and temp not to exceed 79.5 deg
