Green Hair Problem

[DOO-E]

Nobody freak out here but a fellow reefer had this problem. This is what he did and it its working. He has reduced the lights down to 3 watts per gallon. Yet he is still keeping condy anenomes, flower anenomes, and sebea anenomes. All are doing great. He is running 1 150 watt metal halide for the day and 2 actinics for the evening and morning. His hair algea is going away.
