Thoughts on over skimming

I never checked the tank this morning so I'm not sure when this went down but I can home from work today to find that the skimmer had overflowed, it was off by the time I got home but the sump was still foamy and the skimmer cup was full of clear water. I emptied the collection cup Sunday and virtually nothing was in the skimmer on Monday so I don't think a lot of skimmate was dumped in the tank.

The bad part of this story is that virtually all my fish are dead, including my seahorse and lionfish which I've had for close to 20 months. All corals, clams and other inverts seem the same. Overall the tank looks normal, I'm going to test amonia and nitrite right away but I'm guessing these will be normal.

Skimmer is back on regular full duty cycle but I'm completely clueless what happened. This is likely the last straw for me and this hobby at this time, obviously I don't have the proper time and patience to spend on it right now and I just can't handle the extra stress. More than likely everything will be up for sale soon enough but if you have any ideas on what happened please still share them because I would still like to know.

Sorry to hear your lost.
