I just took out the pair of XM 15K bulbs after 9 months and replaced them with Geisman 13Ks. The XMs were very nice for colour, but the par value was terrible. I also switched one of the VHOs to a super actinic to bring the blue back up. Much happier with the lighting now, hopefully my corals will be too.
