Hi! I am new here and first time home and pool owner. When we had our 4-year old pool inspected, the poolman had a list of things he recommended, one of which he called a "hot start" to remove a few rust stains from the bottom of the pool (from previous nails that fell in) as well as to create uniform color since there was some mottling. Completely trusting them and not researching ahead of time, they poured in gallons of muriatic acid. And I mean GALLONS. They poured in maybe 8-16 gallons and left it in 3-4 days and then repeated the process afterwards when the uniformity did not improve. It probably stayed very acidic for around 8-10 days. I had no idea that this would mean we would lose layers and layers of our quartz plaster! This process was done over a month ago and our pool is still shedding and you can actively see plumes when brushing, although it has slightly slowed down some. We are running the Polaris daily and emptying out giant handfuls of white and blue quartz. I am livid. On top of this, our pool ledge is made of flagstone. A few weeks after this process was completed, some of the blue stone had started to turn orange and the grout in between keeps coming off. I run my hands and get brown "sand". Is this salvageable? How long should I expect the shedding in the plaster and grout to continue? My pH is no longer acidic (currently at 8.2) so why is the stone still changing? Please help. Thank you!
