Here is a picture of one the SPS corals that is bleaching at the tips.
Only a couple are doing this.
To be safe and for a possible recovery, I dropped MH down from 175W to 150W.
It could be related to the fact that the Supplier of the Frag did have a mini crash (Calcium Reactor Failure during vacation) and many of his corals got burnt tips. So this could be a burn tip hand me down issue and nothing to do with my tank.
All the Frags purchased earlier are doing fine.
