Red sea Led 90

[9secv6]

So I have innovative marine sr120 its dimensions are 70x24x16. I currently have 3 over the tank with the redsea mounts. I'm trying to look for some advice on intensity? Looking to do a strong mixed reef with some sticks but not a lot. Currently they were set at 20k setting with 100% blue and 50% white. I've had the lights for 1 weeks. My elegance are loving the light as they all came from my Redsea Rs500 that had 10 t5 on it so they are used to lots of light. But I'm already starting to see some cyno forming on the sand bed so I'm feeling light intensity is to much in such a shallow reef. Your talking from the base of the light to the sand bed is less then 24 inches. I know redsea setup the app for everything but I'm worried they could be to stong but nothing is showing signs of bleaching and all the hammers and bubbles are open up big.. should I lower them to 60% if I change the blues to 60% what would u change the whites to. Sorry for the long winded post

I have the red sea led 50 on a nano. I have heard that the red sea lights can bleach and damage stuff toward the top of the tank that doesn't love really intense lighting if you use the default programs. I turned mine down to about 90% intensity on the blue spectrum and 50% on the white spectrum. I would play around with it, but 60% blue seems to low to me, particularly for any SPS. Maybe 70-80% on the blue and turn the white down 10%?

I am looking at putting these over a similar tank. How are they working out for you?

Thanks,

Cyano is from lack of flow. Increase flow.
