Any other suggestions on this it seems all of my corals have washed out color even if they place at the very bottom of the tank?

Try putting it 10-12" above the tank for awhile, then slowly lower it an inch at a time every couple weeks. Maybe someone else will know better but I've seen those ATI fixtures quite high over the tank and still pushing 600 or more par a couple inches under the surface and over 200 par 24" down on the sand bed. They are crazy strong light fixtures

I have my 6x54 about 9" over my 75G. I get good SPS growth and don't fry LPS on the sand bed.

I just put mine at 6 inches above the water and then lowered the lighting time so all bulbs only run for 5 hours a day. After that increase the photo period.

Thanks for the input so far. I think I need to raise it above 6" like I have it now. The bulbs are like 6 months old and still seem to much at 6" above.

I'd put it 12" up and wait till things start to color up again before moving them down. If you are not keeping main light demanding corals you don't really need to move them down
