hair algae during cycle

[likwid]

Hey guys,

My cycle is about a week in now, and I have noticed that one of my rocks is growing hair algae like mad. I think it may have came with some hair algae on it, but it is getting really long now. Is there anything I can do to it during the cycle, or will it die off by itself? Right now i just have a powerhead pointed directly at it, hoping that will discourage growth. I run my halides on for about 6 hours a day, should I just leave the lights off during the cycle? My reasoning for leaving them on during is to avoid and diatom or algae outbreak after the cycle is complete.

Thanks
