That’s a ton of par. I took some readings with a par meter known not to be great for leds, which I have and got 350+ par in most locations on the rock and 200+ on the sand and my sps were paling big time.
I turned back my lights by about 30-40% and color started up. Everyone’s tank is different though.
What lights do you use?
I swapped out a Kessil/T5 hybrid for MH only just 2 weeks ago. I was still getting around 77,000 lux with the 2 360we Kessils at 80%int and 60%color and 4xT5s.


Everyone else might as well forfeit
