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.

looks like that is exactly where your level changes down to the deep end... do you have a robot or vacuum? looks like it runs over that ledge..

It is right where the level changes. I now have a robot vacuum but it appeared before I had it.
The pool guy that I have since fired told me it was calcium buildup (I think) from not sweeping enough after adding the initial salt (which he never told me to do). Told me to dump a bunch of muriatic acid and try to brush it off.

Could you post a complete set of test results? Its unlikely to be calcium deposits, I think.

I'll have to take a sample in. I was getting the water tested weekly and never had an issue according to the store I took the samples to.

It was forming just a couple days after being filled with water. I'm assuming calcium buildup would take a lot longer to form
 
It all depends on the water conditions. I know good test kits are expensive in Canada, but you really should consider getting a Taylor k2006 test kit. You will have accurate, reliable testing whenever you need it without having to take a sample to the pool store.

I have one in my Amazon cart. I'm just waiting on a local store to see if they can get the bigger kit in. Someone on this site mentioned them. I was relying my pool guy but he made a mess of a bunch of stuff beyond this issue, so I've only been looking into this the last couple weeks (since I had my pool opened)
