AI 32HD Mixed Reef 90

[Sevi]

Looking for thoughts opinions on lighting set up/schedule. Running (2) AI Hydra 32s on a 90 gallon standard mixed reef 30-35ish coral, SPS no higher than 2/3 tank hieght. Height of AI fixtures is 13" from water surface, suspended with hanging kit. Peak schedule runs 830am - 530pm begining with a 30 minute ramp up and a slow ramp down till 11pm. See attached for chanel peak intensities. Just want to hear you-all's thoughts, thank you.

I don't have 32s but I have 3 primes over 2 different tanks and I run the BRS AB+ schedule for the last 3 years and get good growth and color. But in all honesty pick I would just pick a preset with that gives you the look you want and stick with it.

I'll get a picture of my schedule, but you never want the lights to turn on point-blank like that. It can be stressful to the fish to go from night to day so abruptly. In my schedule I have a ramp-up period of 4 hours, starting at around 8:00 AM, and after 4:00 PM I start ramping back down until 8:00 PM, where I turn the blues up until around 9:00 when they turn off. The more gradual you can make the sunrise-sunset, the better.
As I said, I will share a screenshot of my schedule in a few minutes. It's worked perfectly fine for me for several years, and though it may not be optimal I get happy corals so I can't complain.

I have 32hds with reefbrites and my ramp up is from 8:30 to 10:30 (blues/violet/uv). Whites come on at 1:30 for 4 hours then off. Blues ramp down 7:30 to 9:00. I run mine way stronger than yours though on a shallow 16" tall tank.
