How long should I have my lights on?

[kwandrsn]

How long should I have my lights on in my reef tank. I've got all kinds of coral I currently have them on:
460\450 blues 10 hrs
14k whites 8 hours
Blues on one hour before and after whites.

Main reason I'm asking is my mushrooms don't seem to be opening like they used to. And I bought a paly or zoa not quite sure which one it is cause it hasn't opened since a got it a few weeks ago. Started to once before and looked orange so maybe a bam bam zoa.

You could cut back on the hours and likely see improved color. I run my actinics in my display 10 hours, and my halides for 8 with great growth and color in my acros.
My frag/lps system however, I run my halides 6 hours and my actinics 8 hours with great color and slower growth. I keep my acans and favia shaded for what seems to give them the best color.

I've experimented by moving them up but all that did was cause them to fade. I think it really depends on what you're trying to grow or keep.

Maybe cut back to 7 on the whites
Only issue with moving corals around is I am running out of room lol
