You dont *need* metal halides. Lots of people run very successful SPS and mixed reefs under T5s. What you should invest in is a timer for your lights. They are so cheap at Canadian Tire for example

One day without lights should not be a problem. My reef goes through that on a regular basis to simulate cloudy stormy days. If I had to guess I'd say it was a coincidence and that your coral was having other issues. How long have you had it? What else is in your tank?

If it still has polyps on it then it is still alive and could recover. If there are ni sign of polyps then it has likely bleached out to death, sorry
