Not sure what lighting you were running before this light.
But if it wasn't led. Be very careful of the intensity of the leds. Go slow ramping the leds up to your desired intensity. As leds are a lot stronger than most people think. If you go to quickly. It will burn your corals.
I second the last post I'm running the 165w mars and when I add new sps I have to turn them down and put in sand bed otherwise I get bad burning.. Be careful and good luck, tank looks good
Yes I've read up quite a bit on the lights. I currently have both the blues and whites on the lowest possible setting. Plan to slowly ramp up over the next 1-1.5 months.
