Alright so everything is back in the 180g, there have been 3 casualties. They were the pocci colony, the neon green one (

), and a frag from Snappy/Coral Master. All the fish made it, and I attribute it to the temp going down, not up.
The fish also seem to have lost some of their mass, so I am kind of pleased I overfeed, because everyone is looking quite a bit skinnier now.
There has been, what I can guess, is browning out of the SPS. It was expected, and I am now taking steps to slowly acclimate everything back to my usual lighting regimen.
Two clams don't look super fantastic, one being the gigas. The gigas however did not smell at all when I pulled it out of the holding tank. I am now in a better position to get better photos. The second clam that doesn't look so great is placed a bit funny. It used to be placed straight up, and now its at more of an angle. I will fix it tomorrow morning and see if that helps things out.
So overall it was very stressful, especially the part with the heaters. We figured out that one of the heaters just stopped working, failed in the off position. The second one failed with the light on, but the heating element not working at all.
