Sorry, I got overwhelmed with traffic -- and it slipped my mind. I'll try to post them today.

I've never seen anything like that, but most of my work has been with concrete pools. However it does not look like something coming from the pool. My guess is either something with the liner itself, OR something behind the liner. I'll ask Waste, who's done a lot of work with liners, to look it it when I get them posted.

But, I'm not hopeful that it's something you can 'clean' away.
