T5 lighting

I have some new t5 lighting I bought a zoomed ocean sun bulb 10,000k and a zoomed ultra sun which now I find out is only 6500k. Its a new tank so I do have brown algae will the 6500 promote growth of the algae and should I replace it with a 10k?

Odds are the brown algae are diatoms. Common in new tanks and consume the silicates in your system. Just need to wait it out. They'll disappear as soon as they showed up. The lights won't make too much of a difference either way.

I think it is a diatom, but recently it started to look like little hairs were appearing on my rocks and it might be hair algae Im not sure. Will it kill corals?

No it won't kill corals. What's your feeding schedule like? If it's not diatoms, your lighting schedule and/or feeding amount/schedule is to blame.
