In a span of a week, many of my corals have died suddenly.
Last week, a giant torch that has been in the tank for over 4 months died within three days, losing many tentacles a day, leaving only a brown stump.
My hammer coral followed the same process a few days later and now it's gone.
This morning I awoke to find the skin peeling off my Jack O Lantern, exposing white skeleton below. I also noticed a small white worm travelling along the edge so perhaps this is the culprit?
I'm also noticing webbing hanging off some of the corals, I have no idea what's going on!
Nothing has been added to the tank for over 2 months.
Temp: 77-78
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: ~20 ppm
pH: 8.2
Alkalinity: 9 dKH
Calcium: 400 ppm
Magnesium: 1,200 ppm
Salinity: 1.025
