Large colonies died over night abhh
 

So woke up today to find my large birds nest colonie almost bleach white and about 1/3 my acro also took a huge beating. I have not touched anything for a few days and water change isn't due for another 2 days....
The only thing I can think of is my room mate dumped something into the tank. Is there any other reasons besides sabbatoge that a volleyball size colonie would die over night??

temp swing, HW malfunction. Any reason to suspect the roomie?

Can't I have the chiller running no chance of flux in heat. my levels where fine all week haven't had time to check since I noticed

Few reasons he hates how my 200 is always pristine with a decent set up and his little tank keeps crashing repeatedly.
And there was a house fight the other night with sum yelling involved.
But I am hardly around so anything is possible

Guess it's possible. Get him drunk and get him to admit it, then kill him :P

Was there a swing in your alkalinity?

Sps can RTN over night. It happens to everyone. If roomie sabotaged something, I would think all the coral would be involved.

there's been quite an increase in death by aptasia zapper lately.. Almost in plague proportions. OR could be the zombie apocalypse

All my corals are looking like $&"" but haven't lost every thing. I have water running threw the R O now so I can do a water change later today

That is my new plan b.

I'll take those skeletons from you ,if you don't want them...
