Is this the dreaded red slime?

I am not sure if this is the dreaded slime but I have it on a few rocks and my sand... What does the pro's think ?

Again Sory for the poor quality of pics, Im still learning how to work the camera :D and thanks for the input.
 
Sand is cyano.
The rocks could be coraline. I have dark red coraline all over my tank.
If you can break it loose on the rock with just a touch, its cyano.
