The full lighting cycle may not have a huge effect on the tanks inhabitants, but it will on the tanks owner.
I'm running 10k 250w MHs with pc actinics. I would klike to try the 14k bulbs on the next change as I find the colour to be a bit too white. I did just replace the Coralife actinics with new Pansonics and the colour is much better, but still not what I'd like to see. Therefore, I'd stick with the 13k in the combo fixture.
