If you add chlorine to a pool that has a silver ionizer, then the ions
combine with the silver and plate out on the sides giving the pool argyria.
They call it staining, but it is the same thing.

There is one company that uses ozonation and copper that claims good results
and no staining. I had one person off list that lives in Vegas (or was it
Phoenix), that said they used that but it was insufficient to keep up with
the organics that blew into their pool.
