See attached pics. I assume this is crystallized calcium. Customer called me about this. Other company did an acid wash and closed up the pool and I'm afraid they did nothing to balance the chemistry. (have not been out to test chemistry yet, but obviously it is off).
From research, seems like some folks have buffed or polished it out. On the last image, you can see the fuzzy crystalline structure extending off the step.
