Hair Algae!

[Trigs]

So i am starting to get a pretty bad case of this HA in my tank, i have never had any problems before until i started my new tank, i ran a 90 gallon for long while with no cases of this and now it comes up and i dont know how to get rid of it, im thinking possibly a big water change? or perhaps scraping it up? anyone else ever had issues with it and resolved the problem quick and efficiently?? i would really like to know!
