Spike in temp killing corals?

[MedcinMn]

Went out of town and my chiller stopped working. Came back to 95* water temp, a few dead corals and fish. Fixed the chiller however I am still losing corals. All chemistry is within normal limits and I've been doing water changes.

This tank has looked great for years until the chiller issue and now continues to do poorly.

My question is can corals be damaged from a spike in temp where they die off slowly? It's been overa month and some corals look like garbage, brain, yellow polyps. Others ie Frogspawn and Hammer look great.

It is possible. The high heat and unknown duration could have certainly damaged them to the point where they are having a hard time recovering.

I had a brain get 1/2 eaten by a angel fish and it looked dead for almost a month but now it's making a comeback. It should work itself out
