Algae problem - Red algae

[alright, while I've been working on my hair algae problem, I noticed that I'm getting some red colored algae. I'm not sure on what exactly it is, but it looks like a thin layer of velvet covering the rock. I've seen alot of it at some of the lfs. What will take care of this? Thanks]
 
[Most likely cynobacteria!

Less nutrients and more flow. So try feeding less and increasing circulation. If you find that no matter what you do it doesn't help then consider dosing a product called Chemi-Clean It works very well but as with any chemical treatment there is always a risk of bad side effects. Having said that it is one of the only chemicals I ever recommend!]
