Some of the corals
Monitors, etc.
After the transfer they looked fine for a day. First a couple frags started to rtn, then more larger ones, until even the larger colonies were on the way out. For some reason a birdsnest frag survived along with my brain coral. All inverts and fish were fine also. My guess is something got in there. Used some flex line for part of the plumbing and despite cleaning it, I think it was bad line. All hard piped now and some of my older flex line.
