ReefAddict April 13, 2020 Share April 13, 2020 Woke up this morning to find my red dragon acro lost 80+ % of its flesh overnight. I know people say they are sensitive, but I’ve never had a problem before. All parameters tested fine. Alk, Ca, Mag. Phosphate and nitrates same as always. Only thing my apex showed out of the ordinary was my ORP was high 451 yesterday for about and hour. My ORP is usually high though. No evidence of pests, and all other acros look happy. Any thoughts? Going to do a water change later today and frag and superglue what I can to hopefully save some of it. Link to comment Share on other sites More sharing options...

Weird thing about SPS is the reaction can come from something prior, like an swing in dKH or temp. When I moved the only coral I lost was my Red Dragon colony, and I found out the only thing that MIGHT have had something to do with anything is my heater wasn't plugged in for a few weeks, whoops! Even stranger, I had a frag on my rack on the other side of the tank.... completely fine.... Link to comment Share on other sites More sharing options...
GraffitiSpotCorals April 15, 2020 Share April 15, 2020 Welcome to the random red dragon rtn club! I am always blown away by large massive colonies of this coral because I have seen so many just go for no reason. Link to comment Share on other sites More sharing options...
Lowefx April 16, 2020 Share April 16, 2020 This is kind of funny to me because my red dragon grows like a weed. On the flip side, i cannot keep acans alive.... Link to comment Share on other sites More sharing options...

GraffitiSpotCorals April 16, 2020 Share April 16, 2020 Yea the tanks where it grows like a weed always have my attention. Well it grows fine for me too if I think about it, just dies from some random blip. Link to comment Share on other sites More sharing options...
dipg April 17, 2020 Share April 17, 2020 Yes, red dragon is finiky. It will grow really nicely for a while and then all of a sudden you will either see STN or RTN. one thing I have noticed is that it doesn’t like a Alk spike. Even a small spike will trigger rtn. Now on the flip side, if you do a course correction by a water change or dosing, it does bounce back. Or if you frag the tips and start over with frags, most of the times the frags will survive.
