the light is more for your coral really wont bother fish , that light is very powerful so it's best to start off with turning the blues on at the lowest setting give things time to adjust maybe a hour or so than turn on the whites lowest setting .
run them all day like that till lights out leave the lights set as they are just shut off the unit . next day turn on lights with the settings you shut off with leave them at that setting a hour or so than turn them up a little run them a few hours look at your corals than turn up a little more and run like that till lights out leaving your last setting ,
now this is basically the same thing all over but as you turn up a little watch your coral
do this till all your coral looks happy lps
and softies you will never go over 1/2 way with the lighting power depending the coral they may want a hair more light ,
now if you have sps
you may need to slowly raise lighting power slowly like you did at the start just be cautious not to raise to fast you can bleach coral with the lighting
I have seen a article in the archive let me see if I can find it and I post the link.
