Something that was said in the first article "Its natural habitat of turbid lagoons indicates that it may benefit from less than pristine water." made me think of something my LFS said to me the other day. Many corals arent doing well that should do well eg. elegence, because reefers are so determined to have prestine water conditions that they are stripping the water of any nutrients it has that these corals need to survive. Just a thought, maybe super clean isnt always super healthy.
