i'm not sure the ballasts are the greatest. the fixture is constructed well, and turns off and on without a hitch. our fixture made the zoos grow really long , as if they were reaching out for the light.
i tried XM 10k, and XM 14k bulbs on it as well, with the same results.
i have since placed all the livestock from that tank in my big tank, and the zoos are already responding differently. worst case scenario, you might have to buy a new ballast or two.
i did, however, have a T Crocea, and a pocillapora frag in that tank that did well, so i don't know for 100% sure. just be aware that it's a possibility.
