What happened my Torch

[Streetlamp]

My torch is a goner. It was my best coral and all of a sudden within I a week it went to this. Sal1.025 phos 0 nitrate 5 calc 440 so all good.

Any ideas? I’ve lost other corals before but this one was a real kick in the teeth.

Having 0 nutrients in the water can play a key issue to what’s going on. Most Euphyllia love having dirty water. I would suggest bringing your nutrients levels up before most issues arise!
