Well 2 weeks agao i noticed my chiller and chiller pump were off line. Temperature reached 90 degrees for several hours and was 84 the morning after when i noticed. I replaced the faulty surge protector which brought the pump and chiller on line. I also changed 40 gallons of water.
Later that day i noticed one of my deep water corals was fading fast. By evening it was clear that it was a gonner. Next day i noticed lots of tissue recession on all my nanas and all my valadia were showing tissue ressesion around the base. My green efflos were very stressed and one had a massive tissue loss on one side. My large purple stag also showed some tissue loss around the base on one side.
After 24 hours or so i noticed all the corals had shifted slightly towards the brown side.
After 3 days I saw a small spot of tissue loss on one branch of my main PM. All the corals had lost some color but most were beginning to show a deeper color and all had good polyp extension. Most of the tissue loss was stabilizing and showed nice sharp edges. The tank was beginning to look better and i didnt think i was going to loose anything except the orginal deepwater that died on the first day. Although the purple monster was looking very good overall i was stll concerned about the branch that had loss some tissue and i fraged it off the main colony.
After 4 days I was sure that all tissue recession had stopped. Colors were stabilizing and the PM was already growing over the fraged area. None of my pm frags on the frag racks showed any stress through this event.
Now for the good part. Its been 2 weeks since the event. The PM is healed and shows the most intense deep purple i have ever seen on a pm. Most of the corals are showing a growth spurt and their colors are getting even more intense then they were before the event. I have included some images for your review.
The areas that showed the most stress on these corals were areas that were allready stressed from prior events. The event seemed to trigger an increase in the zooxanthellae in side the coral. The colors the coral are showing now are deeper and richer than before. Alk demand in the tank is now back to normal. Deepwater corals and corals that had been stressed before were the ones that showed the most damage from the temp spike.
Picture of the tank today.
Here is a close up of the big stag. You can see the tissue recession along the base and you can see the dead deepwater down to the left side of the smaller purple stag in the middle of the tank.
One of my frag racks, some color loss but mostly already back to full speed.
Some color shots.....
All in all i think i was lucky and this system will recover. Through all of this the fish seemed to be unaffected.....
