Lost Coral

[Freenow54]

How is it possible to literally lose a Coral overnight? It was thriving , next day bleached . I don't want to get into parameters now it is closing the barn door after the animal gets out. In the past my parameters were fine except high magnesium which Randy Holmes says is not important . Dose A- K+ weekly water changes . I have one Coral left after starting with over a dozen. Have added An AI Grow , and an AI Glow to fill the gap between my AI primes . set with 0 uv, 75 violet, 71 rv, 116 blue, 82 cw. My Primes are 0uv ,75 violet , 71 rv 0 green , 0 red , no moonlight , 82 cw . Any imput as to what I am missing ? Trying the no Par measurement thing which was a hot debate a short time ago. I own an Apogee but put it away . I don't feed the coral . They are at different levels in the tank. Not a controlled Frag Tank . The lights are off from 7 PM till 6:30 AM

How recently was the lighting change? Could be coral warfare. Could be a parameter change. What kind of coral was it? I’m sorry for your loss. This hobby can be frustrating for sure. We are keeping some finicky critters.

Which coral died? How did it die, I mean did it turn white, melt away, did it fast or slow? How long was the coral in your tank for?

I don't understand your reasoning for not wanting to supply or talk about water parameters? Lighting definitely isn't going to kill a coral overnight. Any pests that you know of?
