crazy purple algae

I have this algae all over my substrate and some on the decorations. I don't think it's coraline. I don't have live rock I'm planning on ordering some this week. So what could it be? It's like a purple color.

probably cyano bacteria, you dont want it in your tank.
there is chemicals that will kill it , but your better of finding out what is causeing the problem, i found out today that my fighting conch eats that stuff so you may want too look into them.

DamselnDistress, are you using RO/DI water? How long has your system been set-up and cycled? What types of inhabitants are currently in your tank?

It sounds to me like cyano. Can you post a picture? If it is cyano, it can be controlled without the use of chemical additives. It is usual;ly caused by using tap water to fill and do top-offs,(use RO\DI if posible) or overfeeding.

Sure looks like cyano. I got it too when my skimmer broke. I still have not gotten rid of it.

oooops! I forgot to mention that you can siphon it out with a turkey baster. I have to do it every day. So far it has not gotten worse, and it is slowly improving.

Another idea you may try is to increase the flow towards the substrate. Maybe angle a powerhead in the areas that it's growing. Sometimes this helps keep cyano at bay.
