Well, I just came back from a 2-day trip to find my tank mid-crash. It seems that last night the timer went on the fritz and never turned off my halides. In true idiot fashion I also managed to have left the fan over my sump off. Temperature was at 89.5 degrees. I quickly turned off the halides, added some ice to the sump, and got the fans going. Only certain loss so far is my beloved cleaner shrimp. All fish are swimming around as normal so far. The corals in my mixed reef are not looking good. A few of the SPS are starting to show signs of bleaching. Is there anything I can do? I'm trying to get the temperature down, but not too fast so as not to add even more shock. Water parameters are good so far. No detecable ammonia, nitrite, or nitrate. PH seemed unusually high. I've started mixing up water for a water change. Any suggestions? I am also ordering a reef keeper elite as we speak.
