Disaster

[Gujustud]

Well I finally got around to hooking up my sump and my overflow.

I've been making up some saltwater over the past few days to fill the sump. Temp was about 1-2 deg higher than the tank, salinty was the same.

I finally turned things on for about a hour, then turned it off. (I had to leave the house, and wasn't 100% satisified things were running 100% so I figured I'd wait till I came home, before letting it run by itself).

I come home a couple hours later and things are in BAD shape.

All my corals look almost dead. Xenia is grey, and completely shrivelled up (more than they do at night time). Looks like they are completely drained. Leather coral which was a nice yellow, is a tiny peice of green. zoo's look somewhat okay.

My clowns were hiding in the rocks, where I've never seen them ever. Couldn't see my little clown goby, finally found him, in the arms of my cleaner shrimp.

My mandarin and firefish are doing completely fine (or so they seem).

I checked my water quality, and everything is good, PH 8.0. I ran to bigal's and got a AquaClear 300 Activated Carbon Insert. I put that into one of the quickfilters on my 802, and I changed the media in the other quick filter.

Just making up some water for a water change. Any idea? Only thing I can think of was that something was in the sump, but I had really cleaned it out with only hot water. I did reseal it up with silicon (I) but that was at least a month ago.
