Help! Wine Red Algea?? Pic

[reefside oc]

There is this red, looks almost like blood, substance growing on our sand. It does not look like hair algea, which we have had before. It seems dense, thick. It seems to be mostly contained to one area and does not seem to be growing. Not sure if this is an algea or what. It has been there prob like 3 or 4 days. Any information would be a huge help.

Sorry about the pictures. Its in the back behind our rock so its hard to get a good shot.

Looks like cyano...Although low flow does not cause cyano..it aids in its growth allowing excess nutrients to accumulate in one spot...
Try to suck it up with a turkey baster, and see if you can get a little more flow in that area.....especially if that's the only place you have it
