Is this green hair algae?

Find yourself some phosphate remover like gfo. if you have a sump i would probably get a reactor to fill with the phosphate removing media. You can also use it just sitting in a mesh bag.

Talk to your stores in your area, they can hook you up.I liked red coral when i lived there

It's Turf Algae, and it will grow for a month or two, but should abate over time, once your tank matures

Keep it plucked and don't let it blow all over your tank
In the meantime ...
When I remove mine, I hold a cup of fresh water in one hand and pluck off the algae ( the whole growth ) with the other, dipping my fingers into the cup to rinse, and carry on with the next clump

It should eventually go away
