You have been pretty vauge about your water you use and the details of your system. Sounds to me like the water you added wasnt good. Do you use tap water or ro? Salinity is deff to high as well, that would do it.

perhaps something else is present, i.e. soap on your hands, grease, copper???

One of the biggest mistakes I made once was that I had a tiny bit of Windex in a kitchen sink where I put down my net. I then used the net in my 5 gallon nano without rinsing the net first. Within hours, the nano crashed and I lost all of the corals in it.
