you need a white light flash light to hit the corals with and see what they look like, most of the vendors i see run 100% blue, last swap i went to the vendors were teasing me (i had set up as a hobbyest) cause i had a little bit of white on, like an 18 or 20k spectrum, they were telling me i would sell more if i ran all blue.
