how to stop rtn?

[Nano]

Well the acro seems to have made it through the night, good polyp extension this morning. I'm sure its too soon to call it ok but I'm glad it made it. Both pieces I fragged off too are alive and well ATM. So if all goes well I'll have my first sps frags for sale.
How long til I know it ok to slowly move it where I want it? I could put it on ky frag rack and slowly raise it to the height I want it over a week or too, would this help acclimate it to the light? What else should i do/know about rtn and sps stress while I'm on the topic?

Thanks everyone for the help
