I'm currently running way more white than normal. We'll see once I start getting some corals in here. I'm probably going to be dropping the white a lot. Also, my Chinese Black Box light is running 1% white but it's a ton. Without it there's a noticeable LARGE blue streak down the center of the tank that just looks gaudy. When I move the other two Noopsyches over it'll be different. My 5 gallon is probably about 20k, my 75 is around 15k, and my 125 is probably around 10k where I tend to run my FW tanks.
