Why the @$&% is my chalice bleaching?

[Zoaelite]

I went through an odd bleaching stage with many of my chalice colonies that I could never really quantize. Really similar to your experiences Kevin but with 7 or 8 whole colonies (and many of those were my nicer ones).

I'm leaning towards some sort of pathogen in the water, all my parameters were pretty spot on including temperature. I had one of the colonies die on me, 2 of them healed extremely quickly, 3 of them took about a month to regain color and my "optimus prime" chalice took a 5 month roller coaster ride to regain its color. It seemed to hit all over the map including Echinophyllia, Mycedium, Oxypora, Pectinia, Physophyllia and Echinomorpha.

Only suggestion I can make step up the target feeding regime and soak the food in the zeovit LPS AA supplement. I know you are good with keeping the parameters steady so keep up on it and hopefully it will come back for you.

Any photos?
