My tank is really loving the 14Ks as opposed to the old 10Ks I replaced. Things are changing color. Pinks, yellows and greens are coming out on things that were mostly brown. I think they are not needing as much symbiont in their tissue and are decreasing it. If it goes too far it will cause bleaching. I don't think that will happen, though. From what I have read it is pretty hard to use too much light on a reef tank.
I have a mixture if soft, LPS, SPS, fish, inverts and plants. What survives is what's in there. I just read that you should not mix types of corals. Good thing I hadn't read that before.
