Thanks guys lights are kessil 360we at about 8 inches from water surface 18inch shallow reef lights are spaced about 18 inches apart to overlap spread it is being runned off by a apex controller with ramped up and down from 6am to 7pm peaking about 45 percent I'll post a screen shot sometimes later today.
ok first off thanks for putting this up. i have been having trouble with my SPS. my set up is almost the same to a T but my alk is about 8.8... my color is set at 50% and intensity is at 80% running the same number of hours using the kessil controller sunrise to sunset.But just bought the apex jr . the SPS will do great for the first month or so then start to go the other way and brown or white out, a few have adjusted and are doing great but I'm not confident enough to purchase more until I've figure it out. It was the light and u may just confirmed that.I had a few people look at it but they're not to familiar with the kessils but based off your chart I'm way too high on intensity. if 45% is your intensity, what is your color setting? Or does the apex match the percent to the intensity? meaning does color max at 45% as well? thanks for your help.

I think your corals were starving you have to try to balance light to nutrient. Some no3 some po4(close to ulns) with low alk 7-7.6 dkh and lower light @ 42-45% on both spectrum depending on my nutrient I also keep my tank a lot cooler about 74-76. If you wanted it to color up.
As far as growth I think high alk at 8.3-9 dkh would be best with Max intensity and color no more then 46%-50%. I sometimes adjust 1-2% higher if I have higher alk with high nutrient no3 and po4 tanks.
