I raised this colony from a frag a year or so ago (growth quickly into a colony). A while ago, I notice some branched died, but recovered. About 3 days ago I noticed half of it were gone

So I frag out 2 branches for safe keep.
then the next day, almost completely wiped out. even the 2 frags

today, as my light comes on, the whole colony is totally whited out except for the foot where some of the polyps remains.
I have been checking water quality and the parameters are quite normal.
I have not change anything. Only thing I did was a 20% water change last week.
Can't figure out what going on, something must have got into the water (undetectable?) or bugs?
Everything else in the tank are fine.
Ahhhh!!!Bummer!!!
