Hair algae or worse

[anewell1321]

My tank fluval evo 13.5 is about 6 months old. For about a month or so I've been having issues with some blooms. I'm not sure if it's hair algae or dinos. I do weekly water changes and try to blow off the rocks with a turkey baster regularly but it's pretty well attached to the rock. About once a week I will try and brush as much off as I can. The issue really only occurs in the upper half of the tank and especially on the bases of my corals. I'm worried I may start to loose some coral. Any advice on what it may be or how to get rid of it would be much appreciated
