I put my hand in the tank while cleaning the glass and went out. Came back about 2 hours later and a third of my corals are curled up and look horrible. I don't have any salt right now for a water change, so I put in a bunch of carbon. The only thing that might have happened (I am totally guessing) is that I washed my hands with soap and didn't give them a really good rinse to get everything off of them before putting my hand in the water. If that's what happened have I basically killed them?
