RTN itself is not contagious, but is an indicator of stress. The source of that stress may be system wide (ie low Ca or red bugs) or local (too much or too little light or water flow in the location for that coral). The fact that it was fragged likely has less to do with it than other sources of stress it has been subjected to in your tank. You have not really given enough info to head you in the right direction for finding the cause... do you test your water? Do you have other sps that are doing ok? Was it RTNing under high light/ water flow? The fact that it survived 2 weeks leads me to believe it is something to do with your tank more than anything.

This was my first tabling acro. I'm using led lighting. I test everything calcium is at 400 alk is 8-9 mag is a little low at 1200 and phos is 0.05(Hanna checker). I placed it a little lower is the tank not directly in light. Maybe the reason I'm keeping other sps some green slimed blue tenius plating montis all at top and some tri colour blue tip lower and a clam inthe sand bed(witch I've had there sometime now) Some of these I've had almost a year and some months. Nitrates nitrate and amonIa is all at 0. I kinda think it was too low in the tank now that I've read more. I see the frags on the rack and there getting great PE well see if therealive tomorrow. I glad to hear it's not contagious. Any other help is much appreciated

If you've only had it for 2 weeks....it may have been destined to RTN.

Also I've never had a acro RTN over redbugs.

Not RTN, but PQTN for sure. I've lost whole colonies, once they started, they were gone in days.
But probably not what happened here. Just a set of parameters that were likely too different to it's source tank. Too much light typically would cause bleaching, too little and it goes brown. PO4 is a bit high, so that could affect it.
Differing flow patterns, often bigger pieces are more affected. The fragging process probably wasn't the cause, I got a 1/3 of a tabling piece 2 months ago that we just cut into three. All three are doing fine in three different tanks.
Unfortunately in the world of SPS, sometimes this happens. If you keep those pieces that you cut off, you got lucky.

also you say LED.... but what LEDs there are alot of different brands and styles to group your lighting into one category.... ive seen LEDs that suck and ive seen LEDs that rock... all being the same wattage....
