How long are you running your lights for? Also, is your tank constantly getting hit with sun light?

no sunlight ....all 6 lights come on from like 9-5  then 2 blues 5 - midnite then moonlights to 6 am then dark 6 to 8 am

even blue lights give off alot of par i would try not running those until midnight because thats a lot of light. Maybe try running lights from 9-8 or something like that.

I agree. That is a long lighting schedule. I would suggest cutting back to a 10 hr - 12 hr max lighting schedule. The moonlights are fine. They won't create any real concerns.

I would keep yout tank in complete darkness for 12 hors a day ..... run 2 bulbs from 8-8 and run the other 4 from 12-6. then after 8 all lights are out

I used to run 2 of my atinics for 10 hrs and all 6 lamps for 6 hrs. My SPS still grew like crazy and I only had to clean the glass once every week or 2. Just gives you an idea of how you don't need such a long light cycle.

Ill shut off the 4 bulbs.  And see if we still get the green algae  and run the 2. Blues
