420nm vs 460nm

[Mantis411]

which wave length will bring out more color in my corals

420 will prob be better for coral growth...however, people more prefer the lighting color of the 460...So, its a preference call really..

agreed. my tanks only run 460 because i get growth from other bulbs. This IMO evens out the colors better with out sacraficing growth potential.
