Can anyone tell me what happened?

[jcampbell]

I just got back to my parents house today, from school. I looked into the tank and noticed my candy cane coral was completely dead! I have had this thing for almost six years and it was one of my favorites. The only thing I can think of is from this past weekend when I was bleaching my Purigen. I followed the EXACT directions on the Purigen instructions for regenerating so I don't see how that would be the issue. All other corals in the tank appear to be fine as well as livestock. If bleach were an issue, wouldn't all my other corals and livestock be dead too? Does anyone have any idea?
The second picture is one of my other corals just to show you they are fine.

Thanks!

Lost mine really fast with no explanation, then it started to come back and died again. I have no idea why. Same thing, nothing else in the tank died, but then I did lose a frogspawn a couple weeks later.

I've heard of no less than 20 people report problems regenerating purigen. For me there are far too many variables in that for something that cost $10 to replace. I'd pull it immediately and add prime to the tank to battle clorine from the bleach.

And that war coral looks slightly irritated as well.

John, did it die suddenly, or over time?

How close is that Favia to it? Is it possible that the Favia stung it? Favias can put out some serious sweepers.

Doubtful it's the Purigen or a result of regenerating it if only one colony is affected. If there was a problem like that, everything would suffer.

Have used purigen for 8-9 years. Never an issue. Always rinse well in container and use a little prime to take remaining bleach out. I let mine soak with prime overnight before putting back in sump. Do not think that is your issue.

Alkalinity swings did in mine earlier this year - it wasn't as nice as yours but it had grown out to 12-14 heads from an initial frag of 4 and been in my tank for 1.5 years.

Parameters?

I'm just now seeing all of these responses! Sorry for the delay guys!

My assumption is that it was Brown jelly disease. I researched it right after it happened. I had some old broken pieces of live rock that used to be in my 75 (that I did not bleach) and just put them in the back of the tank…probably the issue. They are now out of the tank!

It was suddenly. The facia was pretty far away from it. The facia actually started dying off too and I dipped it. It is now starting to look a little better and starting to grow back.
