Need help with algae

[mbailey26]

I just established a new 38 gallon tank and I am getting this brown hair algae on my live rock and some on the sand bed. I was wondering how to get rid of it.

Yes it's reddish brown and my lights are only on about 6 hours but i had them on for 12 for two days then I switched to 6.
