Hi guys
I notice that on the back wall of my tank, when I don't clean it, red algae will start to form. It looks just like normal green algae does, except red. It's not coralline because it scrapes off easily. Could it be cyano or just normal algae build up? There's nothing on the sand or rocks like that either. Thanks!
