The crazy thing is I did a PWC yesterday! About a month ago I did a large water change, about 20 gallons. Used that water to fill up a quarantine tank. My zoas weren't opening before or after that. But everything else has been doing fine up until today... Even the mushrooms are shriveled up.

sure it would, 20000 degrees is a huge amount of heat and would melt your skin instantly even if the water temp changed 4 degrees for corals thats a bit much.

we would never know what fully caused your corals to brown we can just speculate what did but in your case it was totally possible that the short out caused it. in the case of the ops corals deflating i doubt its stray voltage because if the voltage was just sitting in the water the corals and live stock would be sitting at the same potencial so there is no current (amperage) flow, which is what kills. if there was a ground probe i can see it killing things as the voltage would take the path of lease resistance to the source, and when a voltage flows it is being pushed by current through the resistances of the water and conductors

do you have any cucumbers or snails that could have died and released a toxin or even an urchin that could have taken a stroll around the tank over the corals?

Another thing is.. check salinity. A sudden change will cause corals to close up for a few days. I went away for a weekend and for some reason my ATO did not work that weekend. When I got back I had to do a big waterchange and drip fresh water for the next 48hours to bring it down. It went to like 1.030. But after a week everything is fine and back to normal. Just something to keep in mind

Leo, I have a small little yellow filter feeding cucumber that attached to the first rock and has been happy chilling there with his little tentacles outstretched. I also got a black and pink cucumber a few weeks ago to help with the sand bed. He's definitely not dead, as he's roaming around on the front glass right now, which I've read isn't completely uncommon and not necessarily anything to be worried about. Other than that, no urchins or sea apples. I have a green BTA who's content sitting in a pile of rocks towards the bottom of the tank, he doesn't wander around at all. Now that the lights are out, the frogspawn actually look like they normally do at night.

This is baffling... My finger leather are standing upright for the first time in I don't know when, my yellow fiji coral is looking like a champ, the galaxy coral seems to be doing better since the lights went out. My duncans, which I've never had any problems with were closed up most of the afternoon, but have also opened up since lights out. Xenia are pumping away (good luck killing them, right? lol)

Maybe it was just an off day for my tank... who knows...

Salinity is 1.024.

I'm having the exsact same issue's with my corals? I guess this has been going on in my tank for about 2 1/2 weeks. I'm stumped as to what it could be? I've done 2 water changes and gone over everything? This all started for me after I suddenly had a couple of fish die, I was told by a reputable lfs that I had snails spawn causing something some sort of change in water conditions?? Since then I've added a phosban reactor with bio pellets and have seen no changes.

could it be flow? maybe your power heads are a little dirty and less oxygen is beign spread around, cyano can start to form because of this too
