Algae ID Please Hair Algae?

[Hurricane Aquatics]

Hi all,

Bought some WWC frags a few weeks ago and since, I have developed this algae. Not sure if it came in the frags or it is something else. Started tank this year with all new, fresh rock. Is this hair algae or?

Appreciate any assistance. Sorry for the blurry pics, hard to get a good shot.

I believe this is turf algae upon further inspection. Replying to myself lol.

it's hair algae, Have you ever dosed NO3 : PO4-X?

Never dosed that, no. Always used 0 TDS RO/DI water and my nitrates are close to 0. No idea where it came from. I have used Red Sea AB+ Coral food often. I have read stories of that causing algae. Not sure really.
