    I have 2 - 250w CoralVue 20,000K bulbs on my tank right now. I have not see any crazy coral growth with them really....just nice colors.

    I have 2 brand new CoralVue 14,000K bulbs and was wondering if I swap them will the corals be alright with this? Will it hurt them or cause any problems, do I need to acclimate them to the new light...do I need to move anything around?

    Will I get better coral growth?

    Thanks!

    your corals will be fine with the change. You will notice a softer blue color versus the harsher white color.
    I noticed that the corals grow a little slower under 14k bulbs, but the color is much much better

    Coral should grow quickest under 10k, quicker under 14k, and least quick under 20k.
