What should i have my light schedule at?

[DelawareReefer]

I just purchased a pair of Kassil a160's and I'm not quit sure what kind of schedule i should be running them at.. How long should i be running them per day? What intensity? and what coloration is best? I have a mixed reef with some SPS and LPS corals.
If you could please help me out as i would like to avoid over lighting my corals and end up killing them as I've heard of coral acclimation but don't quit understand it and how i should go about it.. thank you
i have a red sea 90 gallon set up...

Acclimating is starting at a lower intensity and/or light period and slowly increasing that.

Other factors that you have not provided would be how high the light is mounted above the tank? What light are you switching from?

A pair of kessil A160's over a 90 gallon tank you'd want to mount them about 5 to 6 inches off the waters surface, start out at lower intensity, approximately 30-35% and slowly ramp it up by 5% a week. On a tank that size you can almost eventually ramp them up to 100%. As far as color, it does not matter. Kessil has designed their lights so that no matter what color you choose, its the correct spectrum for maximum photosynthesis in your corals. It's what kessil refers to as their kessil logic. What most people will do is start out the day at 0% color,and have it ramp up to around 50% color, and then ramp down to 0% color at the end of the day to create dusk and dawn effects. Photo period will all depend on what you want, the average is 8 to 12 hours a day. I keep mine at 10. Hope this helps

Personally I would mount the lights much higher and start the intensity higher as a result as being mounted higher. The higher you mount the light the more spread out the light will be. Granted you may only have enough PAR close under those lights to grow Acropora. BRS did a video on the kessils, I believe they had to use 4 a360 to get adequate PAR levels to grow SPS in a 40 inch wide test tank.
