My SPS appear to have taken a big hit from the recent heat wave a few weeks ago, but it hasn't really shown up until now. I think it is a combination of a temperature spike into the mid to upper 80s during the wave when I wasn't around for a couple of days and my decision to do some rock/flow re-arranging and play with my photoperiod at about the same time.
Everything has been slowly either browning out or bleaching/STNing including my massive blue mille colony that's almost a foot and half across. Even the lousy green digitata is looking kinda sorry.
I was in the process of switching away from SPS anyway, but this appears to have accelerated that. Everything else in the tank - LPS, softies, zoas, clams - came through no problem.
Some of the stuff will hopefully come back over time, but it looks like I'll be having an SPS fire sale at the frag swap. (sigh)
