Coral identification/algea problem?

[gleach]

I think this is a closed brain? It seems to be doing decent but within the last week I noticed this algea growing out of it. Does anyone know what it is bad good? How to take care of it? My tank is 60gal I have a bit of brown algea on the sand bed so my readings could be a bit off but I am using some algea in my sump to eat nitrates. I also have AI Hydra lighting. I'm using a media reactor and I have some chemi pure in it right now. I have one power head for circulation/aeration and it does circulate decently over the coral. My Cal is 370/380 my nitrates are 5.0 my ammonia 0 ph 8.3 kh 10.
