All my SPS corals got bleached out overnight

Ugh. That sucks. How is your dosing handled ? Are you running carbon ? Any creatures whose death could cause this ?

kalkwasser with ATO, have a bag of carbon, no creature dead or alive could be responsible for that.

sure there could be! sea apple death, anemone getting shredded in a powerhead, boxfish, etc. Sounds like nothing like that happened though.

did you just happen to change your GFO? Ive had alk swings/phosphate swings that reealllly made my SPS mad.

I too lost all my sps/lps in this same way. Less than 8 hrs. I believe mine was a temp drop. This sucks that it has happened twice. Is it possible some paly/zoa spawned or released something on both occasions?

What I ment was that it didnt happen in my tank. No GFO at all.

Stray voltage? Do you have some of the same equipment as when it happened the first time?

Sucks man, I've been there. I got you on some SPS frags!

I checked that and wasnt able to measure any voltage. Unless it was an elecrtical spike.

Bogdan sorry to hear that I'm definitely scratching my head right now thinking what in the world it could be....recent change in calcium additives...diffrent salts...heck I don't know at this point. What I do know is that I'll get you a couple of frags to help ya start back up.

I'm sure you already have but try to back track and just look for any change whether it be slight or major...even your ro water or place you got it from...it can all go towards finding out where the culprit will be. I heard of someone who picked up water at a LFS for a water change and he was given ro water instead of salt...which led to the absolute bleaching of everything in the tank and the death of all his fish.

Man threads like this make me paranoid enough to end up getting about 60 test vials and each day just snagging some water. So if this ever happens I have 60 days of logged water to go back over and test for differences or send to a lab.

Yes this seems to be a mystery and figuring it out would be great. With that said I would suggest to run more carbon and add a poly filter. The most logical culprit with all other things being equal(nothing changed) with the exception of introducing the new corals. It would seem some toxin was also introduced at the same time. It happens. Seems it made your corals angry and they expelled a lot of the symbiotic algae which gives them their color. They may recover on their own, but a poly filter may pull the toxin out and the color change on the filter pad may indicate what the problem is.

I don't think bleach white sps are recovering.

I wouldn't count those corals out just yest. Bleached is bad no doubt but unless you get algae growing on them they are not necesaarily dead. IMO I would make sure all is good w/ the water and give them a chance for a possible recovery.
