Kessil a80 sps

[Elmolikesfish]

Hey everyone, I recently acquired a kessil a80 about a month ago and upgraded from the 14 biocube factory compact fluorescents. A lot of my montiporas and one acro near the top of my tank have bleached. The light is about 5"above the tank and was wondering if anyone had % recommendations for % of blue to white and % intensity maybe amount of time you have lights on? I moved bleaching corals lower, but would still love some input. I've also had a couple astreas and hermits die... Not sure if related.
My known levels are:
Nitrates 10 (just added denitrate media yesterday)
Phosphates 0.1
KH 7.5
Alkalinity 480
Salinity 1.025
Magnesium 1440
Temp 76

I've been running lights at 90% intensity and 60% white for about 8 hrs a day

I would reduce the intensity to 50% and slowly increase 5% a month (or 2% a week, depending on how your corals react?) until you reach the tanks limits. As far as color, it's personal preference, but I like anything under 50%. General rule with LED's, never start with max intensity, unless you're switching LED's. If you're changing from one type of lighting to another, start low and slowly work your way up. Corals can survive a lot longer with lower light, than too high of light.
Give it time and be patient.
Good luck!

If you have the controller, its easy. You can set up the acclimation period.
