Roughly 4-5 days ago, my dad’s reef experienced some type of crash resulting in majority of his coral to either die or retract significantly.
He added nitrate to his system rapidly and went from 0ppm to 5ppm overnight and at the same time switched brands of salts and performed a water change. I theorize one of or both of these happening at the same time resulted in his crash.
Tonight he brought over all “surviving” Euphyllia hoping my system could possibly save them.
I dipped all coral in CoralRx for 10 min and kept the water moving/agitated the whole time. Afterwards I rinsed off in clean new salt water for another 3-5 minutes. I placed all coral on the sand bed to give them the most chance as possible to make a comeback.
Based on their appearance and how retraced they are into their skeleton, I am pretty skeptical if any will make it.
Any thoughts or suggestions for anything that could possibly help these guys out?
