When I got home late last night I checked on my frag tank. Everything looked normal. I come home today from work and almost all of the SPS
corals have massive white sections. It's as if the tissue has just disappeared!
All water parameters, temperature, and salinity seem to at typical levels. This is a tank that has been doing quite well for weeks. The mushrooms and zoas still seem to be doing just fine.
Not really anything to do at this point except to try and understand what happened.
Has anybody ever had such an experience?
