Anenome not Acclimating to New Lights

[LeanneP]

I have recently got an anenome and some coral frags and I am having a very hard time with them and the lights. Andrew (previous owner) had Ati T5 and I have 2 x 250 watt metal halides. We raised my lights about 6 iches higher and I am only running one light at a time. I have been slowly increasing the lights but everything will look happy one day and the next everything has closed up and even more so when the halides are on. I was up to 3 hours on the side with the corals and 1 hour on the side where the nem was, everything looked great and next day they were all closed. I have checked all levels and everything is good. I have less then 2.5 nitrates.
So my question is do I raise lights even higher up and should I just keep increasing lights or turn them off if things are not looking happy. I have a lawnmower blennny so a little concerned his food will run out if lights aren't running much.
Any nem experience would be appreciated.
