My pool was finished in May 2021. I recently noticed that there is white scaling above my water line. Can / should I be doing anything to clean it up? I tried rubbing it off by hand but it is not going anywhere.

Following up on this earlier thread with same name, I have some white scaling deposits above the water line. I tried the pumice stone suggested without luck.

I had a pool guy out to install a SWG for a salt water conversion. He suggested a 50/50 mix of water + muriatic acid in a spray bottle, squirt it on, and it should run right off. Good idea or bad?
