help! coral dying fast...

[Maverick00]

Hey guys, i just bought a new coral 2 days ago and it seemed to be doing well for the first two but then slowly started to turn white and loose the little blue "furry looking bulbs" it has on the branches in the last 12 hours. Appears to be spreading fast. Im unsure of the name of this coral but here are some pictures.

I did have it close to a powerhead which i now moved thinking it was possibly to much waterflow.

Should i move it lower in the tank, could it be possible it is being blasted with too much light? lights are on for 4 or 5 hours a day.

Should i break off the affected branch?

Any other tips would be great... thanks.
