I just replaced my 7,000K lights on my fresh water tanks to 10,000K deep
reef lighting to see if my plants may do better. And you are right the
colour is more blue. Both my fresh and salt water tanks get plenty of
dappled sunlight so this is something of a test. I realize that plants
and coral are two different things, but both photosynthasize so I am
wondering if the light requirements for both low light planta and low
light coral would be reasonably similar. By the way my plants are doing
great and have surpassed my wildest dreams. And I have been reading up
on low light corals and even some which do not need any light.

Any one else done similar research? Any ideas would be welcome.
