same thing happened to me about 5 months ago with a clip on light... not to be the bearer of bad news but everything died with the exception of 2 pieces of SPS and my frogspawn... it took several weeks for the fish to die... I hope that my experience was not the norm for your sake... best of luck and I would do lots of water changes and run lots and lots of C
Good luck
