Reef Radiance DM 155e

To anyone else who owns one of these fixtures-how high do you have it hung over the water line? What percentages did you begin at and what do you run now? And does anyone have any par values? Any feedback is appreciated as my corals don't seem too happy with the light and I'm unsure whether they are getting too much light or not enough

I have had mine for about a month or so and I have kept mine at 20% whites and 50% blues and so far so good. I previously had 4 par38's from ledtric so my corals are used to LED's but par38's were real spotty, now with 2 DM155E's over my 90g my tank is completely illuminated. I do not have a par meter so I am also very interested if anybody has any numbers.

I haven't run leds before so its difficult without a meter to tell whether i have the right amount of light. Its hanging about 16 in off the water with 45% blue %25 white (I raised these today cause I thought they might've been set too low)

You have to hang them pretty high, as the light spread is pretty focused; but is also depends on your water depth. I'd say one covers about a 24X24 area pretty nicely. My tank is 30X 30, so I have it WAY up there.

I'm wondering if maybe they were not turned up high enough rather than being turned too high? I had them on maybe 30% blue 10% white. Wondering if that wasn't enough?
