Actually, it just struck me, but the boxes should be the ballasts for the halides. The ballasts for the PC
's should be in the hood, or one box is for the halides, other is for the PC
's. I would check the hood first, if necessary to change the ballasts.
As far as the anemone, the halides would be just fine.
I would try to price everything out from a best-worst case scenario, to help your decision. Best of luck, whichever route you choose!
