Blue lights

[Jvesche20]

I currently have ocean revive t247 they are black boxes. I love just the blue part of the lights. For a few hours in the morning and at night I have blue on and white off. Will it matter if I have just blues on all day or do my corals need the rest of the colors? I have mainly sps

Corals need a dark period

Well of course. I keep lights on for 11 hours. During the 11 hours is it fine to keep only blues on or do they need the white spectrum

You can lengthen the blue period and shorten the whites. I would still have the whites on for 4-6 hours for coral health and color. You can set it up to have the whites on when you are at work or when you are least likely to view the tank.
