Just remember to use an annual photo period instead of a daily one. Arctic and antarctic corals need 24 hours of intense white light in the summer and only a couple hours of dim blue light in the winter.
For my arctic corals I use just my actinics for about an hour a day in December and run 1,000 watts of 10,000k for 24 hours in June. It's great that I can collect my own corals when I visit Nome.

P.S. There really are arctic corals and anenomes, they're soft corals similar to the Hawaiian black corals and are non-photosynthetic. The University of Alaska Museum of the North has a display on them. And the Seward Sea Life Center has several tanks with live specimens.
