Does any one have these and are they any good for Fish AND Corals. I know in asking "corals" that there are soft and hard corals, as a newbie, I havent figured out whats what in that category...If the marineland Reef Lighting will work on 1 type, I'd be pretty set with that option... Does anyones LFS use these in a DT in the store??? Opinions? Thoughts??? Thanks, Aaron
