Can I add coral to a tank

[Dive_dry]

My question is can I add coral to my tank that I have to let run foul for 3 mounts as it got hit with velvet it will have no fish in it. : I don't want to rise the white flag.

I shut down my 70 I had running for 3ys it was mostly a softy tank now I want to do SPS and I would like to at least get the coral started while the tank runs its course . It has been running since the end of oct. fish all but 1 went tu last week
