    8 to 8.8 dKh shouldn't be so low as to make a coral bleach nearly instantly....

    I imagine that bleaching from the bottom up can be leaching of phosphates from the rock into the coral's skeleton....

    Could be posible because I have only been using ro/di water for about 8 months. The first 13 months tap water was used. I had a monti cap come with the acro and it is OK tho.

    This is the first time it has happened to me. The only real change is the amount of GFO used for filtration. I increased the amount to recommended levels about 2 weeks ago. No problem with the corals that were in the tank already.

    I bought 5 acro frags,monti cap, and some chalices. Everything is fine except for 2 of the acros. 1 of the acros is a tenuis and the other is some kind of brancher that are doing poorly. The other 3 acros are a humulis and 2 other stubby peices that seem fine with polyps out. Maybe it's just bad luck but now I'm thinkig about getting rid of all softies.

    I think it is bad luck, I have very few softies, good flow and use carbon. None of the other corals are having any problems.
