Nice Chalice! I'd love to keep one, but every chalice frag I've tried has bleached out. I've tried them a couple times in my horse tank under 150w MH. It's a 24" tall tank, and I've tried them mid-level, low level, shaded, and even up high. If you've kept them before, can you give me any pointers? I'd love to keep a large chalice in my 110g display, but I'm afraid my LEDs would fry the heck out of it!
