Led light schedule

[Proteus]

I was wondering about light schedule and if higher output shorter hours is different from longer hours less intensity.

Right now my radion is running at 90% 18k for 8 hours. My orange grove which is about 6" deep has turned slightly yellow. All coral grows great and has nice color. Just wondering if changing lights % or duration would be good idea

I find that under my radions, all my corals change colour a bit. Do you have a ramp up/ramp down period?

[Proteus]

yeah i ramp up about a hour in am of shcedule and a hour and half in pm which is mostly night lights as i like the glow of the sps

i have a light blue acro that is finally getting its blue back. i have a little understanding of pigments and symbiotic algae and its growth and decline based on nutrients and light.and the pigments produced. i have very low nutrients which i know colors will be pale and pastel. i just want to be able to have optimal lighting and water quality.
