Is it safe to use a diluted mixture of say 2:1 or 1:1 solution of muriatic acid and pool water to spray onto those natural stone tiles and then use a scrubby pad or wire brush to remove it? (Safe meaning that it won't harm my stone) I've got the pool chemistry stabilized now so that we will avoid the scale in the future, but this is above the water line due to a TON of rain/thunderstorms which prevented me from getting out there to make sure the pH stayed where I usually want to keep it.....now the scale has formed all the way up to the coping above the water line. Gotta get that stuff off very soon while my pool temperature is still at least 76 degrees (burrr), any colder and I definitely won't be getting in there!
I am now keeping the CSI slightly negative to prevent it coming back.....we unfortunately have a high CH level - 460.
Many thanks!
