Basically whenever I've seen it it was due to stress. Either a sudden change in salinity, pH, Temp, who knows really. It could be that the water added was O2 depleated. I have also heard stories that some people who sell water (no names mentioned) don't change their filters regularly and will sell basically tap water (chlorine and all) as RO/DI.
I'm not saying this is the case but I would question it. If you havent already and the shroom is still upchucking I would add some dechlorinator, check the pH and Alk.
