went to frag swap last sunday, and brought home a truckload of stuff. some of the stuff was various corals. i acclimated the corals and then placed them in my tank. that was sunday evening. as of today, two fish are dead, and another one looks pretty bad. what did i do wrong. and what can i do to fix this. water tests show everything is ok, except my nitrites are just a bit high. i am pretty new to all of this, so any help is appreciated. thanks.
