Heat kills deadly

[Willito]

Just an update on the situation.

With the lid removed from the sump, an 8" fan blowing on the water surface, and the halides off for the day, the temperature lowered by 10 degrees in less than 12 hours. It is now sitting around 80F. The remaining corals are starting to come back out, not looking great, but much improved. Some corals sustained minor tissue fold-back, but I hope in time it will heal and grow back to replace the damaged areas.

I must admit, yesterday was pretty stressful. Let me tell ya, this is one lesson to be learnt and kept for a long time. Thanks to everyone who contributed in helping me bring this around.
