My pool was installed late last year and it was only open for a few weeks before being closed. Only a couple days after it was filled up a very faint line started to appear. The guy who installed and treated the pool said he would take care of it before closing for the winter, but never did
I just recently opened it and after treating the water and having it clear up I noticed the white line is much more apparent. See attached.
It does not come up with brushing.
I was wondering what would be causing it and what is best to remove it. I have a vinyl liner.
