Thanks for the tip.
And did you notice this across the span of the tank or just directly under the leds. It doesn't look like those narrow little clusters would do much, but my LFS ran the demo mode with just the LEDs and I was surprised at how they pretty much lit up the entire 4' cube.
At higher power you could probably get away with using only the LEDs on the fixture. The spread is decent because they use reflectors in the LED clusters rather than optics.
Most of the corals higher up and closer to the clusters were unhappy.
