    Most of the photos I see on these forums from people who are successful at growing corals look very blue. My light has a blue and a white setting. The light is not real strong, so I assume I should set the blue at 100% but I'm wondering where to set the white. I'm also wondering how many hours per day to run it.

    The blue look is typically to make the colors pop more for pictures, also blue LEDs come through pretty strong unless you start using filters and things on your camera. So I wouldn't judge many photos to be a true representative to the colors as you would see them in real life.

    what kind of light do you have? Is it programmable to ramp up/down, or is it just an intensity you can set for each color and turn the light on and off?
    I would add enough white until you get something that looks pleasing to you visually. Then see how the corals react.
    As for how many hours I think most people would be at least 8-10 hours at "full" light on their tanks. Controllable lights you probably see that number stretched out a couple more hours for a sunrise and sunset ramp.

    @blackx-runner@blackx-runner pretty much summed it up but just to throw one thing out there. The club has PAR meters one can borrow and measure in your tank!...would recommend.

    I have a Current USA Orbit Marine LED. I've been told It's pretty weak for corals, but I can program it to precisely do whatever I want. I've been using a pre-programmed setting that ramps up for an hour, then runs at full intensity for 8 hours, then ramps back down for an hour. Full intensity looks more white than blue, so that's the reason for my question. I thought I might tweak it a little, and I was wondering where to set the percentage on the white. I'm getting a little film algae on the glass too, so I thought cutting back on the white might help with that.

    I'm working on a DIY clear mesh cover for my tank right now, but I may borrow the PAR meter once it's finished. I'm fascinated by test equipment, so that would be really fun to play with.

    A little less white light and more blue can help with algae issues.
