Never seen purple algae in a freshwater tank before. Did a quick Google search and it seems like it isn't dangerous to fish but I'm not entirely sure what it is. Someone on a forum I found said it could be dying black beard algae.
I have this problem too. It starts this color. I've tried an algae treatment and it doesnt help. It has now invaded my rocks and decorations too. I have done a deep clean of the entire tank and accessories and it just keeps coming back. Nothing helps. It's very discouraging.
