Hey Mike, nice to see you finally got some. I would try the blues from 8-8, and the whites from 12-4 just to start. And if they have dimmers that's a plus. I would start them 18" off the top of the water, but I would need to know the depth of the tank, etc. If you got 50%white/blue, the whites are going to be really strong. Your SPS will love it. But you don't want to overdo it there, my friend. There is a bit of trial and error but it will be worth it in the long run!!!
