Tank crash caused by Wal Mart fan!

[Lance]

Today was warm so I turned the fan on the sump for the 90g corner tank. Later I walked by the tank and immediately knew something was wrong. Fish were acting very strange, and the tank was murky. Looking closer I saw that all the softies and LPS were closed up, and the SPS sliming badly. I couldn't see anything obvious in the tank so I looked in the sump and found the fan had become disengaged from its base and fallen into the water. I pulled the plug out of the receptacle and removed the fan, then quickly changed out the carbon in the reactor and changed 15 gallons of water. The sump is running on a GFCI outlet, but the fan was plugged into a wall receptacle because I just use it once in awhile in the summer. (Damn that Murphy and his stupid law!)
Fish seem okay but all inverts are affected: 2 cleaner shrimp are MIA; snails look to be dying as do the Feather Dusters; clam is closed; all zoas, palys and mushrooms are closed up; all LPS are closed and SPS are sliming like crazy, which may be a good thing: if they're still sliming they're still alive.
Will wait awhile and do another water change. (Keeping fingers crossed here that it isn't as bad as it looks at the moment).
