I didn’t turn it on, however midday I had turned it off because I was adding the yellow tang and he was spazzing out without the lights off. Then I slowly turned them back on each hour increasing the intensity by 15 till I got to 60 and then it slowly went back down as it usually does. The time of this video/photos was much after it had been turned off.Did you turn the lights on last night and wake them up? You might have stressed them some and that can cause some fish to pale out.
