When I first switched to mp10's I used it but then I went away with work that meant I didn't get to use it. Something I noticed is that some of my corals don't seem to like night mode, when I use night mode my Duncan and torch both close up tight but when I don't they stay more open at night and seem happier. This is just my experience with it, I'm sure others will disagree which is fine.
My other thought when I stopped using it is that the ocean doesn't really stop at night, or not 80% like my mp10 do.
Personal experience other may vary
