Blue light increase at night

[dnprall]

I have my light intensity set at 50% for both blue and white for my Red Sea LED90.

I like how the blue only lights make the coral glow but it’s hard on the eyes for all day use.

Would I cause harm if I were to increase the blue light to 100% and decrease white to 10% for the last hour before my moonlight cycle? My thoughts were to be able to see the tank glowing at the end of the night before I head to bed. Is this too much of a wild swing?

What's you're describing is what most people do when they can control light spectrum throughout the day.

In the morning start off with a more blue spectrum, mid day ramp up to an AB+ spectrum and then ramp back down to a blue spectrum in the evening.

wouldn’t say it’s all that bad, i do that at night so i’ve got an hour to watch with all blue and feed AB+ and watch it glow lol

My lighting is two actinc blue XHOs, one actinic T5 and one 50/50 T5. My lights are on for 16hrs a day. The T5s are only on for 5 of those hours from 3pm to 8pm, the rest is just the XHOs at this schedule. Doesn't show well in the graph, but some of the ramps are 30 minutes.

Most people do a solid blue bit of time before lights out.
