I can grow anything in my tank but chalice. They survive but dont grow. Have tried moving them all over the tank. Now they are in the shade but still not looking like most of you guys chalice. I have sps, acans, favia etc... and all do very well. So what's the deal? I have 30 3w crees and 2 18w t-5s for lights. mg 1350, calcium 400
