Coral help!!!

Ok, let's get down to details, or this is going nowhere:

What size tank?
How many watts of LEDs?
What distribution of colors? (actinic, 10k, 12k, etc.)
How high are they above the surface of the water?
How far down are the corals from the surface of the water?
Are the corals in the shade?
Is there something (acrylic, glass, mesh) in between the tank and the lights?
How long are the lights on for? Timer or by hand?

We need answers to every one of these questions to help you.

 

The tank is a 46g. The LED's have 170w with 28 whites at about 10k(they say 10k-12k) and 20 blues and 8 violets. The light is right at water level (do to canopy) with nothing between it and the water. The corals have been within 12" of the light with no shade. the lights are timed to have the blues come on at 11:00am, whites at about noon and off around 8pm, blues off around 9pm. Hope that helps, and thanks for all your help;D. sorry to be such a noob. I should know more since my tank has been setup for 7 years...but a neglected 7 years
