New light acclimation period

[cmor1701d]

I finally upgraded my lights. I'm getting the Coralife Aqualight Pro HQI with 3-150w 10k [acronym:aa823000d7="Metal halide light"]MH[/acronym:aa823000d7] and 4-96w [acronym:aa823000d7="Power compact fluorescent"]PC[/acronym:aa823000d7] actinics.
I currently have 2 Coralife fixtures with a 92w-10k and 92w-[acronym:aa823000d7="Actinic lighting"]03[/acronym:aa823000d7] actinic in each.
My lights are on from 1pm - 11 pm for the actinics and 2-10 pm for the 10k PCs.

I have an closed brain, open brain ,a candy cane some leathers and [acronym:aa823000d7="Mushroom coral"]shrooms[/acronym:aa823000d7] currently in the tank.

I have some screen material to mask the tank top with 3-4 layers of material.

My question is how long do I leave each layer on before removing one?

This is assuming the same photo period for the [acronym:aa823000d7="Metal halide light"]MH[/acronym:aa823000d7] but an increase of a couple of hours for the actinics?

OK, I finally got the light and bulbs shipped separately so no broken bulbs this time. I put the light on the tank last night.

Am I better not screening the tank and using just the actinics for the full photo period and start slowly adding the [acronym:9de4b74e16="Metal halide light"]MH[/acronym:9de4b74e16] lights. If so, how long should I start with the [acronym:9de4b74e16="Metal halide light"]MH[/acronym:9de4b74e16], 1hr/day, 2hr/day? And how often should I bump that up by a half-hour?

If using the screen material is better then my question remains. How long should a layer be on before removing it? 2-3 days, a week?
