    If it's at the tips, are you sure it's bleaching? It might just be growing. Can you give us a picture?

    Certain Acropora species contain pigments and coatings that could mimic the bleaching process, however, it could be just the growing process, as Curt pointed out or just the coloration associated with the tips of that particular coral.
    Picture will help!

    Also how has your alkalinity been and how is it now? Alkalinity changes/instability can cause the tips to "burn" or "bleach".

    Probably not clog them. How long were they "blasted" by the powerhead? If they were like sitting right in front of a powerhead in a straight stream of water that can start to literally blow the flesh off of coral but Acropora really love a lot of flow so it would take a lot, or a good amount only coming from one direction for a while I believe.

    I'm pretty sure that the "bleaching" on the tip is just new growth on the coral. nothing to be concerned about.
