Still steady at around 81 as of this morning! Much relieved. I can hear my corals smile, as my wallet gently weeps.
Sadly I did have casualties but hopefully no more. Purple bonsai, icefire echinata and green slimer have all RTNed. The echinata is a bone white skeleton but the bonsai and slimer still have a touch of tissue clinging to them. I'm pretty sure the slimer is a goner, can see 'threads' of tissue still peeling off... But the bonsai appears to have stopped. Whether it can recover is tbd though - what is left is extremely pale.
A couple of the lower branches on my hulk are whitish but I can't tell if its tissue loss or not. I was just starting to get some good polyp extension on it within the past week so I am hopeful its just discolouration due to shade...
